The wide and fast spread of COVID-19 around the world has led to a dramatic increase in the need for protection products both for carers and for populations. Surgical team protection includes a systematic screening of patients, wearing protection devices by all the operating staff, and adequate management of aerosols. The risk of aerosol dispersal is particularly high during laparoscopic and robotic surgeries due to the interaction between circulating CO2 and surgical smoke that may contain small viral particles. To decrease the risk of virus transmission, many recommendations have been implemented including the use of integrated insufflation devices comprising smoke evacuation and filtration mode. Such devices are lacking in many centers around the world and to overcome this urgent unmet need, we designed a cost-effective filtrating suction as a more readily available alternative.

Background: A new, self-contained, digital, continuous pump-driven chest drainage system is compared in a randomized control trial to a traditional wall-suction system in cardiac surgery., Methods: One hundred and twenty adult elective cardiac patients undergoing coronary artery bypass graft and/or valve surgery were randomized to the study or control group. Both groups had similar pre/intra-operative demographics: age 67.8 vs 67.0 years, Euroscore 2.3 vs 2.2, and body surface area 1.92 vs 1.91 m 2 . Additionally, a satisfaction assessment score (0-10) was performed by 52 staff members., Results: Given homogenous intra-operative variables, total chest-tube drainage was comparable among groups (566 vs 640 mL; ns), but the study group showed more efficient fluid collection during the early postoperative phase due to continuous suction (P = .01). Blood, cell saver transfusions and postoperative hemoglobin values were similar in both groups. The study group experienced drain removal after 29.8 vs 38.4 hours in the control group (ns). Seven crossovers from the Study to the Control group were registered but no patient had drain-related complications. The Personnel Satisfaction Assessment scored above 5 for all questions asked., Conclusions: The new, digital, chest drainage system showed better early drainage of the chest cavity and was as reliable as conventional systems. Quicker drain removal might impact on intensive care unit (ICU) stay and reduce costs. Additional advantages are portable size, battery operation, patient mobility, noiseless function, digital indications and alarms. The satisfaction assessment of the new system by the staff revealed a higher score when compared to the traditional wall suction chest drainage system., (© 2020 The Authors.

Background: Percutaneous aspiration with sclerotherapy (PAS) and laparoscopic marsupialization (LM) are minimally invasive treatment modalities for renal cysts. We aimed to compare the efficacy and cost/effectiveness of LM and PAS for the treatment of simple symptomatic renal cysts. Methods: Data were prospectively collected from three health care institutions in which 80 patients with symptomatic simple renal cysts underwent a single session of PAS with 95% ethanol (PAS group, n  = 40) or underwent LM under general anesthesia (LM group, n  = 40) between March 2012 and May 2016. We compared the patient profile, duration of procedure, duration of hospital stay, radiological and symptomatic success rates, treatment costs, and incidence of complications between the two groups. Results: At the 6-month follow-up, the radiological success rate in the LM group was significantly greater than that in the PAS group (97.5% versus 60%; P  < .001). The symptomatic success rate was comparable in the two groups (95% versus 90%; P  = .675). The treatment failure rate did not significantly differ between the two groups (5.0% versus 17.5%, P  = .154). The mean total cost in the PAS and LM groups was 1256 USD and 2343 USD, respectively ( P  = .001). No significant between-group difference was noted regarding the overall complication rate ( P  = .615). Conclusions: Both LM and PAS are effective and safe procedures for the treatment of symptomatic simple renal cysts. A single session of PAS seems to be a cost-effective method for the management of symptomatic simple renal cysts.

Percutaneous nephrolithotomy (PCNL) is a commonly used type of minimally invasive treatment in kidney stone surgeries. Surgical success is assessed according to residual stone amount after surgery. The purpose of this study is to compare the two methods' success and practicality that are applied after the fracture of the stone in the patients who applied PCNL and which enable the removal of the residual stones. Among 102 patients who underwent a single-session of PCNL at our department between June 2015 and November 2016 were evaluated. Previously identified irrigation method and our aspiration method which described used in post-operative patients divided into two groups of residual fragments was assessed by computed tomography. The results were evaluated in statistical analyses. Significant p was accepted as p < 0.05. The age and gender distribution of patients in the irrigation and aspiration groups did not differ significantly (p > 0.05). In irrigation and aspiration groups, stone size did not differ significantly (p > 0.05). The amount of residue stones and dust remaining in the irrigation group was significantly higher (p < 0.05) than the aspiration group. Although many methods have been tried before, we think that the aspiration method we have described is a cheaper, more effective and feasible option.

Background: Fluid samples obtained from an affected joint still play a central role in the diagnosis of periprosthetic joint infection (PJI). It is the only preoperative test able to discover the causative microbiological agent. In the hip, fluid aspiration can be performed through fluoroscopy, ultrasound, or, less commonly, computed tomography. However, there is still a lack of consensus on which method is preferable in terms of efficacy and costbenefit., Purposes: We, therefore, asked whether (1) the benefits in terms of sensitivity and specificity and (2) the costs were comparable between fluoroscopy- and ultrasound-guided joint aspirations in a suspicious of hip PJI., Methods: Between 2013 and 2016, 52 hip aspirations were performed on 49 patients with clinical, radiological, or serological suspicion of PJI, waiting for a revision surgery. The patients were divided in two groups: fluoroscopy- (n = 26) vs ultrasound-guided hip aspiration group (n = 26). These groups were also divided in control and infected patients. The criteria of MusculoSkeletal Infection Society (MSIS) were used, as gold standard, to define PJI., Results: (1) Ultrasound-guided aspiration revealed valid sensitivity (89% vs 60%) and specificity (94% vs 81%) in comparison with fluoroscopic-guided aspiration. (2) The cost analysis was also in favor of ultrasound-guided aspiration (125.30€) than fluoroscopic-guided aspiration (343.58€)., Conclusions: We concluded that ultrasound-guided hip aspiration could represent a valid, safe, and less expensive diagnostic alternative to fluoroscopic-guided aspiration in hip PJI.

Objective: To evaluate the clinical and microbiological factors associated with skin and soft tissue infections drained in the emergency department (ED) vs operative drainage (OD) in a tertiary care children's hospital., Methods: This was a cross-sectional study among children aged 2 months to 17 years who required incision and drainage (I&D). Demographic information, signs and symptoms, abscess size and location, and wound culture/susceptibility were recorded. Patient-specific charges were collected from the billing database. Multivariate regression analysis was used to determine factors determining setting for I&D and the effect of abscess drainage location on cost., Results: Of 335 abscesses, 241 (71.9%) were drained in the ED. OD for abscesses was favored in children with prior history of abscess (odds ratio [OR], 3.18; 95% confidence interval [CI], 1.36-7.44; P = .01) and labial location (OR, 37.81; 95% CI, 8.12-176.03; P < .001). For every 1-cm increase in size, there was approximately a 26% increase in the odds of having OD (OR, 1.26; 95% CI, 1.11-1.44, P < .001). Methicillin-resistant Staphylococcus aureus was identified in 72% of the 300 abscesses cultured and 12.3% were clindamycin resistant. OD was more expensive than I&D in the ED. Per abscess that underwent I&D, OD is $3804.29 more expensive than I&D in the ED while controlling for length of stay., Discussion: Clinical factors associated with OD rather than I&D in the ED included history of abscess, increased abscess length, and labial location. Microbiological factors did not differ based on I&D setting. For smaller, nonlabial abscesses, ED drainage may result in significant cost savings., (Copyright © 2016 Elsevier Inc.

Background: Keeping the operating field clean and visible is an important technique in neurosurgery. Continuous irrigation-suction (IS) of the surgical field is currently often done using devices available that are expensive and demand technical proficiency. We report a simple method of continuous IS using a widely available central venous catheter and a controlled suction cannula., Methods: We used a controlled suction cannula attached to a central suction system. A single lumen central venous catheter is passed through the keyhole of a controlled suction cannula, which is connected to a continuous irrigation system., Results: The operative field was clean throughout the procedure, obviating the need for an assisting surgeon to irrigate into the deep operating field and, hence, reducing the duration of surgery., Conclusions: The proposed IS system could be surgeon friendly, easily manageable, yet cost-effective and efficient., (Copyright © 2016 Elsevier Inc.

In a consecutive series of 536 unilateral primary total hip arthroplasties (THAs) and 598 unilateral primary total knee arthroplasties (TKAs), the use of a post-operative drain was associated with $538 additional cost per THA, and $455 for TKA. The use of a drain increased hospital length of stay (LOS) for THA, but not for TKA. In both groups, the use of a drain increased estimated blood loss (EBL) and increased the amount of allogeneic blood transfused. Over the 10-week period, drain use was associated with a total cost of $432,972 for our institution. Data from this study would favor a selective approach to the use of drains in primary joint arthroplasties., (Copyright © 2014 Elsevier Inc. All rights reserved.)

Blood donation is an essential step in transfusion medicine that must take into account the donor's welfare, collection effectiveness, and blood product quality. This prospective study enrolled 13 canine blood donors, each subjected to both gravity and suction collection methods, in a randomized order. Clinical parameters, including heart rate (HR), respiratory rate (RR), systolic blood pressure (SBP), and rectal temperature (RT), were evaluated at four time points, including when the donor was on the floor and on the collection table, and before and after blood donation. The number of times the donor and needle required repositioning, the duration of the donation, the noise created by the apparatus, and the presence of a hematoma were evaluated. The weight, index of hemolysis, and hematocrit of each unit of blood were recorded. There was no significant difference between collection methods for either the clinical parameters at each time point or the prevalence of hematoma formation, the frequency of needle repositioning, the hemolysis index, or hematocrit. Collection by suction was noisier (P < 0.0001), faster (P = 0.004), and associated with significantly less donor repositioning (P = 0.007). Suction appears to be a safe and cost-effective method that should be considered to optimize blood donation.

The objective of this investigation was to verify the impact of the learning curve involved after the introduction of a novel electronic chest drainage device on the duration of chest tube usage following pulmonary lobectomy. Propensity score case-matched analysis was used to compare the first consecutive 51 lobectomy patients managed with an electronic chest drainage (E) device with 51 controls managed with a traditional device (T). There was no difference in the characteristics of the two matched groups. Compared with patients managed with a traditional device, those with the electronic one had 1.9-day shorter duration of chest tube drainage (2.5 vs. 4.4 days; P<0.0001) and a 1.5-day shorter hospital stay (4.5 vs. 6 days; P=0.0003). Consequently, they had an average reduction in hospital costs of €751 (€1802 vs. €2553; P=0.0002). Compared with those in group T, patients in group E had a consistently shorter duration of chest tube use in relation to the very first patients treated. The learning curve sloped down for the first 40 patients before reaching a plateau, when the maximum benefit of using the electronic device was evident. Compared with traditional devices, the use of a novel electronic chest drainage system was beneficial from its initial application. The inherent learning curve was short and did not affect the efficiency of the system.

Purpose: Closed endotracheal suctioning (CES) may impact ventilator-associated pneumonia (VAP) risk by reducing environmental contamination. In developing countries where resource limitations constrain the provision of optimal bed space for critically ill patients, CES assumes greater importance., Materials and Methods: In this prospective, open-labeled, randomized controlled trial spanning 10 months, we compared CES with open endotracheal suctioning (OES) in mechanically ventilated patients admitted to the medical intensive care unit (ICU) of a university-affiliated teaching hospital. Patients were followed up from ICU admission to death or discharge from hospital. Primary outcome was incidence of VAP. Secondary outcomes included mortality, cost, and length of stay., Results: Two hundred patients were recruited, 100 in each arm. The incidence of VAP was 23.5%. Closed endotracheal suctioning was associated with a trend to a reduced incidence of VAP (odds ratio, 1.86; 95% confidence interval, 0.91-3.83; P = .067). A significant benefit was, however, observed with CES for late-onset VAP (P = .03). Mortality and duration of ICU and hospital stay were similar in the 2 groups. The cost of suction catheters and gloves was significantly higher with CES (Rs 272 [US $5.81] vs Rs 138 [US $2.94], P < .0001). Nine patients need to be treated with CES to prevent 1 VAP (95% confidence interval, -0.7 to 22)., Conclusions: In the ICU setting in a developing country, CES may be advantageous in reducing the incidence of VAP, particularly late-onset VAP. These results mandate further studies in this setting before specific guidelines regarding the routine use of CES are proposed., (Copyright © 2011 Elsevier Inc. All rights reserved.)

Objective: To establish whether continuous subglottic suctioning (CSS) could be cost-effective., Design: Cost-benefit analysis, based on a hypothetical replacement of conventional ventilation (CV) with CSS., Setting: A surgical intensive care unit (SICU) of a tertiary care university hospital in France., Patients: All consecutive patients receiving ventilation in the SICU in 2006., Methods: Efficacy data for CSS were obtained from the literature and applied to the SICU of our hospital. Costs for CV and CSS were provided by the hospital pharmacy; costs for ventilator-associated pneumonia (VAP) were obtained from the literature. The cost per averted VAP episode was calculated, and a sensitivity analysis was performed on VAP incidence and on the number of tubes required for each patient., Results: At our SICU in 2006, 416 patients received mechanical ventilation for 3,487 ventilation-days, and 32 VAP episodes were observed (7.9 episodes per 100 ventilated patients; incidence density, 9.2 episodes per 10,000 ventilation-days). Based on the hypothesis of a 29% reduction in the risk of VAP with CSS than CV, 9 VAP episodes could have been averted. The additional cost of CSS for 2006 was estimated to be €10,585.34. The cost per averted VAP episode was €1,176.15. Assuming a VAP cost of €4,387, a total of 3 averted VAP episodes would neutralize the additional cost. For a low VAP incidence of 6.6%, the cost per averted VAP would be €1,323. If each patient required 2 tubes during ventilation, the cost would be €1,383.69 per averted VAP episode., Conclusion: Replacement of CV with CSS was cost-effective even when assuming the most pessimistic scenario of VAP incidence and costs.

Background: The aim of this randomized controlled trial was to assess the possible benefit of using a new haemostatic agent (Hémoionic) in the pelvic cavity in sphincter-saving surgery for rectal cancer., Methods: Eighty-five patients undergoing elective sphincter-saving rectal resection for cancer were randomized into Hémoionic (41 patients) and control (44) groups. In both groups, a pelvic suction drain was left in place for as long as the daily output exceeded 20 ml. The primary endpoint was volume of fluid collected by the suction drain; secondary endpoints were duration of drainage, and postoperative mortality and morbidity rates., Results: The mean total drainage volume was significantly lower in the Hémoionic group (453 ml versus 758 ml in control group; P = 0.031). There was no significant difference between groups in duration of drainage and morbidity. The mortality rate was four of 41 in the Hémoioni group and one of 44 in the control group (P = 0.192)., Conclusion: Hémoionic may reduce the drainage volume after sphincter-saving surgery for rectal cancer, but offers no clinical advantage., Registration Number: ISRCTN79721331 (http://www.isrctn.org)., (Copyright (c) 2010 British Journal of Surgery Society Ltd.

Objectives: Human milk (HM) feeding is associated with lower incidence and severity of costly prematurity-specific morbidities compared to formula feeding in very low birth weight (VLBW; <1,500 g) infants. However, the costs of providing HM are not routinely reimbursed by payers and can be a significant barrier for mothers. This study determined the initial maternal cost of providing 100 mL of HM for VLBW infants during the early neonatal intensive care unit (NICU) stay., Methods: This secondary analysis examined data from 111 mothers who provided HM for their VLBW infants during the early NICU stay. These data were collected during a multisite, randomized clinical trial where milk output and time spent pumping were recorded for every pumping session (n = 13,273). The cost analysis examined the cost of the breast pump rental, pump kit, and maternal opportunity cost (an estimate of the cost of maternal time)., Results: Mean daily milk output and time spent pumping were 558.2 mL (SD = 320.7; range = 0-2,024) and 98.7 minutes (SD = 38.6; range = 0-295), respectively. The mean cost of providing 100 mL of HM varied from $2.60 to $6.18 when maternal opportunity cost was included and from $0.95 to $1.55 when it was excluded. The cost per 100 mL of HM declined with every additional day of pumping and was most sensitive to the costs of the breast pump rental and pump kit., Conclusions: These findings indicate that HM is reasonably inexpensive to provide and that the maternal cost of providing milk is mitigated by increasing milk output over the early NICU stay.

Objective: To compare the therapeutic effects of aspiration via a directional soft tube and conservative treatment in patients with mild hemorrhage in the basal ganglion., Methods: Seventy-five patients with mild cerebral hemorrhage (10~30 ml) were randomly divided into two groups for aspiration treatment with minimally invasive directional soft tube placement (minimally invasive group, n=36) and conservative treatment (medication group, n=39). The patients in the two groups had comparable mean GCS scores of 11-15 on admission. The clinical outcomes of the patients were compared between the two groups., Results: In the minimally invasive group, complete removal or absorption of the hematoma occurred within an average of 3.8 days, significantly shortened in comparison with the 24 days in the medication group. The short-term (1 month) follow-up of the patients showed good neurological recovery in 58% of the patients in the minimally invasive group, significantly greater than the rate of 29% in the medication group; 6 months after the treatment, good neurological recovery was achieved in 50% of the patients in the minimally invasive group, but only 16% in the medication. No death occurred in the minimally invasive group, and 2 patients died in the medication group. The cost of hospitalization averaged 5136.3 Yuan in the minimally invasive group and 11843.6 Yuan in the medication group., Conclusion: Compared with conservative treatment, the minimally invasive treatment with soft tube placement can significantly shorten the hospital stay, promote neurological function recovery, lower the mortality rate, and reduce the cost of hospitalization.

Background: Simple aspiration is recommended as first-line treatment for all primary spontaneous pneumothoraces requiring intervention. However, the optimal salvage treatment remains unclear when simple aspiration is unsuccessful for controlling symptoms. In this study, the safety, efficacy, and estimated costs of video-assisted thoracoscopic surgery (VATS) and chest tube drainage (CTD) were compared., Methods: Between 2002 and 2007, 164 patients with a first episode of spontaneous pneumothorax were managed by simple aspiration. Among them, 52 patients underwent subsequent VATS (30 patients) or CTD (22 patients) due to unsuccessful aspiration. The demographic data and treatment outcomes of the two groups were collected through retrospective chart review., Results: Postoperative analgesics use did not differ between groups. Complications developed in 2 of the VATS group (6.7%) and 6 of the CTD group (27.3%), with mean hospital stays of 4.8 and 6.1 days, respectively (p = 0.034). Patients in the VATS group had lower rates of overall failure, although the rates of immediate failure were not significantly different. After a mean follow-up of 16 months, recurrent ipsilateral pneumothorax was noted in 1 VATS patient and 5 CTD individuals (p = 0.038). The estimated total costs per patient were $1,273 in the VATS group and $865 in the CTD group., Conclusions: Although associated with higher costs, VATS rather than CTD is the preferred salvage treatment for unsuccessful aspiration of the first episode of primary spontaneous pneumothorax, because of shorter hospital stay and lower rates of overall failure and recurrence.

Background: Suction drains are widely used in vascular surgery, despite the absence of specific evidence that they confer benefit to patients. There has been no systematic review of the available evidence, though drainage has been shown to confer no benefit, or indeed harm, across a variety of surgical disciplines. Accordingly, a systematic review and meta-analysis of the current evidence base for closed suction drainage following surgical lower limb revascularization was undertaken., Methods: Medline, Embase, trial registries, conference proceedings, and article reference lists were searched to identify randomized controlled trials of the use of surgical drains. The primary outcomes were wound infection, seroma/lymphocele formation, and hematoma formation. Pooled odds ratios were calculated for categorical outcomes., Results: Four trials containing 429 groin wounds were eligible for inclusion. There was no significant effect on wound infection, seroma/lymphocele formation, or hematoma formation., Conclusion: Our meta-analysis suggests that no benefit is conferred by wound drainage following lower limb revascularization. The practice incurs avoidable expense and should not be routinely used.

We have assessed the evidence that closed tracheal suction systems (TSS) prevent ventilator-associated pneumonia (VAP), using a meta-analysis of randomized controlled trials (RCTs). We searched PubMed and Cochrane databases to identify RCTs that compared closed with open TSS for the management of mechanically ventilated (MV) patients. Nine RCTs were included in the meta-analysis. There was no difference in the incidence of VAP between patients managed with closed and open TSS [odds ratio (OR)=0.96, 95% confidence intervals (CI) 0.72-1.28]. There was no heterogeneity among the eligible trials (I2=0, 95% CI 0-0.65). The compared groups did not differ with respect to mortality (OR=1.04, 95% CI 0.78-1.39) or intensive care unit (ICU) length of stay [two RCTs: 12.3 (sd 1.1) vs 11.5 (1.4) days and 15.6 (13.4) vs 19.9 (16.7) days]. Suctioning with closed systems was associated with longer MV duration (weighted mean differences: 0.65 days, 95% CI 0.28-1.03) and higher colonization of the respiratory tract (OR=2.88, 95% CI 1.50-5.52) than open TSS. The available evidence suggests that closed as opposed to open TSS usage did not provide any benefit on VAP incidence, mortality, or ICU stay of MV patients.

This meta-analysis of the three RCTs that have compared topical negative pressure with conventional treatment in patients with lower limb ulcers found that it significantly reduced healing times and increased the number of healed wounds.

A review of the evidence base for the use of vacuum-assisted closure (VAC) therapy is presented, analysing both experimental and clinical data.

There is little evidence to suggest the appropriate frequency for changing suction canisters and tubing in the gastroenterology setting. This survey was initiated to determine whether there was a community standard for this issue. A diverse geographic response from attendees at the 2006 Society of Gastroenterology Nurses and Associates revealed that there is no current "standard of practice." Findings were diverse and are reported on the basis of the size of the facility, type of facility, number of endoscopic procedure rooms, and number of endoscopic procedures per month. The majority of respondents (91%) used disposable suction devices. The authors recommend the need for well-designed, systematic studies to determine the appropriate frequency for changing suction canisters and tubing in the endoscopic setting.

Aims: The aims of this study was to determine whether an active policy of cost curtailment would impact on the theater cost of laparoscopic surgery in a pediatric setting; to document the extent of cost changes over time and to identify factors that adversely influence expenditure; and to investigate whether the surgeon is a significant factor in the price of the procedure., Materials and Methods: A prospective audit of laparoscopic procedures was performed in a single unit over a 36-month period. Detailed costs of theater inventory for all procedures were compiled on a case-by-case basis and recorded on a database. The cost of six index procedures were collated and changes over the period of the study analyzed. The factors responsible for increased expenditure were flagged and appraised to enable the implementation of cost-saving measures. The prices of the laparoscopic equipment were based on invoiced figures provided by hospital managers, and no long-term outcome measures were taken into account., Results: A total of 179 cases were performed by six surgeons over a 3-year period between January 1, 2003 and December 31, 2005, with no adverse intraoperative events. The procedures studied in further detail were appendicectomy (n = 50), fundoplication (n = 25), cholecystectomy (n = 12), nephrectomy (n = 10), Fowler Stevens for undescended testes (n = 10), and modified Palomo operations for varicocoele (n = 7). The mean cost of these procedures fell year by year over the period of study but was significant only in appendicectomy (P = 0.017). For this procedure, there was a significant difference in costs between the various surgeons (P = 0.007), but this trend was not noted with the other procedures. There were no major intraoperative events, although 2 patients required conversion owing to technical difficulties posed by the cases. Among the factors that influenced costs were the use of disposables, particularly for hemostasis and suctioning, and an inability to procure reuseable instruments., Conclusions: The costs of commonly performed laparoscopic procedures are falling year by year. The surgeon is a factor in the costs of some procedures. A cost-saving strategy has not been compromised of patient safety; however, some cost-saving measures, though attractive, are labor intensive and are not practical. An overall commitment to the sensible use of health care resources translates into savings for hospitals, thereby strengthening the case for laparoscopic surgery.

Background: Closed suction systems (CSS) are increasingly replacing open suction systems (OSS) to perform endotracheal toilet in mechanically ventilated intensive care unit patients. Yet effectiveness regarding patient safety and costs of these systems has not been carefully analyzed., Objective: To review effectiveness of CSS and OSS, with respect to patient outcome, bacterial contamination, and costs in adult intensive care unit patients., Data Source: Search of MEDLINE, CINAHL, EMBASE, and Cochrane databases and a manual review of article bibliographies., Study Selection: Randomized controlled trials comparing CSS and OSS in adult intensive care unit patients were retrieved., Data Extraction/synthesis: Assessment of abstracts and study quality was performed by two reviewers. Data were combined in meta-analyses by random effect models. Fifteen trials were identified. No significant differences were found in incidences of ventilator-associated pneumonia (eight studies, 1,272 patients) and mortality (four studies, 1,062 patients). No conclusions could be drawn with respect to arterial oxygen saturation (five studies, 109 patients), arterial oxygen tension (two studies, 19 patients), and secretion removal (two studies, 37 patients). Compared with OSS, endotracheal suctioning with CSS significantly reduced changes in heart rate (four studies, 85 patients; weighted mean difference, -6.33; 95% confidence interval, -10.80 to -1.87) and changes in mean arterial pressure (three studies, 59 patients; standardized mean difference, -0.43; 95% confidence interval, -0.87 to 0.00) but increased colonization (two studies, 126 patients; relative risk, 1.51; 95% confidence interval, 1.12-2.04). CSS seems to be more expensive than OSS., Conclusions: Based on the results of this meta-analysis, there is no evidence to prefer CSS more than OSS.

The literature suggests that topical negative pressure can be an effective treatment for severe pressure ulcers. However, research is needed on its effects on variables such as dressing change frequency, quality of life, pain relief and cost-effectiveness.

Background: Tracheal suctioning costs are higher with a closed tracheal suction system (CTSS) than with an open system (OTSS), due to the need for complete daily change as recommended by the manufacturer. However, is it necessary to change the closed system daily?, Objective: To evaluate the tracheal suctioning costs and incidence of ventilator-associated pneumonia (VAP) using closed system without daily change vs OTSS., Design: Prospective and randomised study., Setting: An Intensive Care Unit in a university hospital., Patients: Patients requiring mechanical ventilation., Interventions: Patients were randomly assigned to CTSS without daily change or OTSS. We used a CTSS that allowed partial or complete change., Measurements and Results: There were no significant differences between both groups of patients (236 with CTSS and 221 with OTSS) in gender, age, diagnosis, APACHE-II score, mortality, number of aspirations per day, percentage of patients who developed VAP (13.9 vs 14.1%) or the number of ventilator-associated pneumonia per 1000 days of mechanical ventilation (14.1 vs 14.6). There were not significant differences in tracheal suctioning costs per patient/day between CTSS vs OTSS (2.3+/-3.7 vs 2.4+/-0.5 Euros; p=0.96); however, when length of mechanical ventilation was lower than 4 days, the cost was higher with CTSS than with OTSS (7.2+/-4.7 vs 1.9+/-0.6 Euros; p<0.001); and when length of mechanical ventilation was higher than 4days, the cost was lower with CTSS than with OTSS (1.6+/-2.8 vs 2.5+/-0.5 Euros; p<0.001)., Conclusion: CTSS without daily change is the optimal option for patients needing tracheal suction longer than 4 days.

An effective electric breast pump is an important tool for the management of breastfeeding challenges such as provision of human milk to sick or premature infants. A breast pump is also, in Western culture, critical for breastfeeding mothers who return to work. Obtaining an effective electric breast pump can be particularly difficult for uninsured or impoverished women because of the expense, complicated insurance reimbursements, and scarcity of providers that supply breast pumps to the inner-city community. To address this problem at Boston Medical Center (BMC), an inner-city hospital that serves a poor and minority urban population, members of the Breastfeeding Center worked with a local charity and local insurance companies to increase access to pumps for all women at BMC and to guarantee that every breastfeeding mother with an infant in the neonatal intensive care unit receive a double-setup electric breast pump, regardless of her insurance status or ability to pay.

Objective: Topical negative pressure (TNP) (vacuum therapy) is frequently used in the management of acute, traumatic, infected and chronic full-thickness wounds. This prospective clinical randomised trial compared the costs of TNP with conventional therapy (moist gauze) in the management of full-thickness wounds that required surgical closure., Method: The direct medical costs of the total number of resources needed to achieve a healthy, granulating wound bed that was 'ready for surgical therapy' were calculated., Results: Fifty-four patients admitted to a department of plastic and reconstructive surgery were recruited into the trial. Cost analysis showed significantly higher mean material expenses for wounds treated with TNP (414euros+/-229euros [SD]) compared with conventional therapy (15euros+/-11euros; p<0.0001 ), but significantly lower mean nursing expenses (33euros+/-31 euros and 83euros+/-58euros forTNP and conventional therapy respectively; p<0.0001). Hospitalisation costs were lower in theTNP group (1788euros+/-1060euros) than in the conventional treatment group (2467euros+/-1336euros; p<0.043) due to an on average shorter duration until they were'ready for surgical therapy'. There was no significant difference in total costs per patient between the two therapies (2235euros+/-1301euros for TNP versus 2565euros+/-1384euros for conventional therapy)., Conclusion: TNP had higher material costs. However, these were compensated by the lower number of time-consuming dressing changes and the shorter duration until they were 'ready for surgical therapy', resulting in the therapy being equally as expensive as conventional moist gauze., Declaration of Interest: This work was partly supported by the Plastic and Reconstructive Surgery Esser Foundation, and KCI Medical, Houten,The Netherlands. The authors have no conflicts of interest.

Most chronic wounds are caused by arterial or venous vascular disease. Wound care is an interdisciplinary task and economic challenge. Numerous new wound dressings and treatment methods have been introduced recently. Basic research has enhanced our understanding of stimulation and inhibition of wound healing. Well-constructed clinical studies have shown some traditional approaches to be effective and others, less so. Successful wound healing requires treatment of the underlying disease as well as correction of local factors that may delay healing. The choice of dressings must be based on continuous re-assessment of the wound. Modern approaches for the most common types of chronic wounds, as well as options such as vacuum treatment and tissue-engineered skin are presented along with information on latest rules for reimbursement for wound care in Germany.

Negative pressure wound therapy is one of the dominant adjunctive wound care modalities used in North America. One company has a proprietary hold on the market for this type of wound therapy and recent wound care literature has focused on the company's products rather than on the concept itself. Currently utilized standards for negative pressure wound therapy are based on a few relatively recent publications originating after 1997. However, a review of the English and Russian literature that predates this work reveals discrepancies regarding optimal duration of treatment, intensity of negative pressure, mode of application, timing of application, and intervals between treatments. A careful review of research that has rarely been cited in recent wound care literature elucidates the inconsistencies between currently held dogma and less well known negative pressure research. In order to achieve optimal outcomes of care, current practices must be re-evaluated and researched using well-established guidelines for determining treatment safety and effectiveness.

Objective: The aim of this study was to analyze the prevalence of ventilator-associated pneumonia (VAP) using a closed-tracheal suction system vs. an open system., Design: Prospective and randomized study, from October 1, 2002, to December 31, 2003., Setting: A 24-bed medical-surgical intensive care unit in a 650-bed tertiary hospital., Patients: Patients requiring mechanical ventilation for >24 hrs., Interventions: Patients were randomized into two groups; one group was suctioned with the closed-tracheal suctioning system and another group with the open system., Measurements: Throat swabs were taken at admission and twice a week until discharge to classify pneumonia in endogenous and exogenous., Main Results: A total of 443 patients (210 with closed-tracheal suction system and 233 with the open system) were included. There were no significant differences between groups of patients in age, sex, diagnosis groups, mortality, number of aspirations per day, and Acute Physiology and Chronic Health Evaluation II score. No significant differences were found in either the percentage of patients who developed VAP (20.47% vs. 18.02%) or in the number of VAP cases per 1000 mechanical ventilation-days (17.59 vs. 15.84). There were also no differences in the VAP incidence by mechanical ventilation duration. At the same time, we did not find any differences in the incidence of exogenous VAP. Likewise, there were also no differences in the microorganisms responsible for pneumonia. Patient cost per day for the closed suction was more expensive than the open suction system (11.11 US dollars +/- 2.25 US dollars vs. 2.50 US dollars +/- 1.12 US dollars, p < .001)., Conclusion: We conclude that in our study, the closed-tracheal suction system did not reduce VAP incidence, even for exogenous pneumonia.

Background: An earlier randomized, controlled trial showed that weekly or as-needed (as opposed to daily) changes of in-line suction catheters were associated with substantial cost savings, without a higher rate of ventilator-associated pneumonia (VAP). To examine the impact of decreasing the frequency of in-line suction catheter changes in our medical intensive care unit, we conducted an observational study, comparing the catheter costs and frequency of VAP during (1) a control period, during which in-line suction catheters were changed daily, and (2) a treatment period, during which the catheters were changed every 7 days or sooner if needed, for mechanical failure or soilage., Methods: All adult patients admitted to our 18-bed medical intensive care unit were evaluated for the 3-month interval 1 year prior to the practice change (May through July 1998) and for the 3 months after implementing the new policy (May through July 1999). To avoid bias related to usual seasonal variation in VAP frequency, we also determined (via medical records) the VAP rate during May through July 1997. The occurrence of VAP was ascertained by an infection control practitioner, using criteria established by the Centers for Disease Control and applied in a standard fashion. The VAP rate was calculated as the mean number of VAPs per 100 ventilator-days for each 3-month interval. Use of ventilators, humidifiers, and non-heated-wire, disposable circuits was uniform during the study, as were policies regarding humidity, temperature settings, and frequency of routine ventilator circuit changes., Results: During the control period 146 patients accounted for 1,075 ventilator-days and there were 2 VAPs (0.19 VAPs per 100 ventilator-days). During the treatment period 143 patients accounted for 1,167 ventilator-days and there were no VAPs. The mean +/- SD duration of in-line suction catheter use during the treatment period was 3.8 +/- 0.8 days, and 51% of the patients had the same catheter in place for > 3 days (range 4-9 days). The actual cost of catheters used during the treatment period was lower than during the control period ($1,330 vs $6,026), predicting annual catheter cost savings of $18,782., Conclusions: We conclude that (1) a policy of weekly (vs daily) change of in-line suction catheter is associated with substantial cost savings, with no significant increase in the frequency of VAP, and (2) to the extent that these findings confirm the results of prior studies they support a policy of changing in-line suction catheters weekly rather than daily.

Objectives: To compare aspiration and sclerotherapy using sodium tetradecylsulfate (STDS) with open hydrocelectomy in the treatment of hydroceles with regard to safety, efficacy, and cost-effectiveness., Methods: Patients with symptomatic hydroceles were prospectively enrolled in an aspiration and sclerotherapy protocol between October 1998 and June 2000. Patients in this group underwent percutaneous aspiration followed by sclerotherapy with an STDS-based solution. This group was compared with a group of patients chosen consecutively who underwent hydrocelectomy between December 1996 and August 1999. Primary outcome measures included patient satisfaction and procedural success. Secondary outcome measures included complications and comparative costs., Results: A total of 27 patients with 28 hydroceles were enrolled in the aspiration and sclerotherapy protocol and compared with 24 patients with 25 hydroceles in the hydrocelectomy group. Mean follow-up for the aspiration and sclerotherapy group and hydrocelectomy group was 8.9 and 16.4 months, respectively. Patient satisfaction was 75% for aspiration and sclerotherapy and 88% for hydrocelectomy. The overall success rate for aspiration and sclerotherapy was 76% compared with 84% for hydrocelectomy. The complication rate was only 8% in the aspiration and sclerotherapy group, but 40% in the hydrocelectomy group. Comparative costs per procedure demonstrated that hydrocelectomy was almost ninefold more expensive than aspiration and sclerotherapy., Conclusions: In the treatment of hydroceles, aspiration and sclerotherapy with STDS represents a minimally invasive approach that is simple, inexpensive, and safe but less effective than hydrocelectomy. Aspiration and sclerotherapy is a viable first-line therapeutic option in the management of hydroceles.

Study Objective: Endotracheal suctioning in intubated patients is routinely applied in most ICUs but may have negative side effects. We hypothesised that on-demand minimally invasive suctioning would have fewer side effects than routine deep endotracheal suctioning, and would be comparable in duration of intubation, length of stay in the ICU, and ICU mortality., Design: Randomised prospective clinical trial., Setting: In two ICUs at University Hospital Groningen, the Netherlands., Patients: Three hundred and eighty-three patients requiring endotracheal intubation for more than 24 h., Interventions: Routine endotracheal suctioning (n=197) using a 49-cm suction catheter was compared with on-demand minimally invasive airway suctioning (n=186) using a suction catheter only 29 cm long., Measurements and Results: No differences were found between the routine endotracheal suctioning group and the minimally invasive airway suctioning group in duration of intubation [median (range) 4 (1-75) versus 5 (1-101) days], ICU-stay [median (range) 8 (1-133) versus 7 (1-221) days], ICU mortality (15% versus 17%), and incidence of pulmonary infections (14% versus 13%). Suction-related adverse events occurred more frequently with RES interventions than with MIAS interventions; decreased saturation: 2.7% versus 2.0% (P=0.010); increased systolic blood pressure 24.5% versus 16.8% (P<0.001); increased pulse pressure rate 1.4% versus 0.9% (P=0.007); blood in mucus 3.3% versus 0.9% (P<0.001)., Conclusions: This study demonstrated that minimally invasive airway suctioning in intubated ICU-patients had fewer side effects than routine deep endotracheal suctioning, without being inferior in terms of duration on intubation, length of stay, and mortality.

Objective: Wound infections after cardiac surgery carry high morbidity and mortality. A plethora of management strategies have been used to treat such infections. We assessed the impact of vacuum-assisted closure on the management of sternal wound infections in terms of wound healing, duration of vacuum-assisted closure, and cost of treatment., Methods: Between November 1998 and June 2001, a total of 27 mediastinal infections were managed with vacuum-assisted closure. Group A (n = 14) had vacuum-assisted closure as the final treatment modality, whereas in group B (n = 13) vacuum-assisted closure was followed by either a myocutaneous flap (n = 8) or primary (n = 5) wound closure. The choice of additional treatment modality was based on wound size., Results: In group A, 4 patients died and a satisfactorily healed scar was achieved in 64% of cases. Median durations of vacuum-assisted closure and hospital stay in group A were 13.5 days (interquartile range 8.8-32.2 days) and 20 days (interquartile range 16.7-25.2 days), respectively. Mortality was 7.7% in group B, with a treatment failure rate of 15%. Median duration of vacuum-assisted closure in group B was 8 days (interquartile range 5.5-18 days), and median hospital stay was 29 days (interquartile range 25.8-38.2 days). During the year before institution of vacuum-assisted closure, poststernotomy infection (n = 13) was managed with rewiring and closed irrigation system. Treatment during this year failed in 30.7% of cases (n = 4/13), and mortality was also 30.7%. The total cost (hospitalization and treatment) per patient for vacuum-assisted closure was 16,400 dollars, compared with 20,000 dollars for the closed irrigation system treatment., Conclusion: Vacuum-assisted closure, used alone or before other surgical treatment strategies, is an acceptable treatment modality for infections in cardiac surgery with reasonable morbidity, mortality, and cost.

Use of topical negative pressure, also known as VAC, gradually increased throughout a trust following its success in a burns and plastic surgery unit. A trust-wide centralised approach set out to standardise its use and to reduce costs.

Background: Women undergoing surgery for primary breast cancer routinely have suction drains inserted deep to the wounds, which are removed approximately 6-8 days after operation, requiring a period of stay of that duration in hospital. The aim of this study was to perform a prospective randomized clinical trial to evaluate a new surgical technique of suturing flaps without wound drainage, combined with early discharge, in women undergoing surgery for breast cancer., Methods: A total of 375 patients undergoing surgery for breast cancer were randomized to conventional surgery or suturing of flaps with no drain. The main outcome measures were length of hospital stay, surgical morbidity, psychological morbidity and health economics., Results: Suturing of flaps and avoiding wound drainage in women undergoing surgery for breast cancer resulted in a significantly shorter hospital stay. Adopting this surgical technique with early discharge did not lead to any difference in surgical or psychological morbidity. Health economic benefits to the National Health Service resulted from saved bed days with no impact on community costs., Conclusion: Wound drainage following surgery for breast cancer can be avoided, thereby facilitating early discharge with no associated increase in surgical or psychological morbidity.

The aim of this study was to evaluate a policy of early discharge at 48 hours with suction drains in situ in a cohort of patients undergoing surgery for breast cancer and to compare this with a similar cohort of patients discharged 5 days postoperatively. This was an integrated qualitative/quantitative study using a questionnaire given to both groups providing comparable results by using averages and percentages to describe and synthesize the data. A questionnaire of open and closed questions was given to 19 patients who chose to be discharged at 48 hours with drains in situ, and 16 patients who opted to be discharged at 5 days after drain removal. The study demonstrated that patients regarded early discharge as being safe and were satisfied with their care when they were given a high level of support from hospital and community staff. The results also identified that it was important for patients to make their own decision about either early discharge or standard discharge in order to be satisfied with the outcome of their care.

The manual syringe method of cleaning endoscopes involves numerous problems, including cross-infection, contamination, wasted time, and employee safety issues. This article describes the development of an alternative system by a nurse entrepreneur for endoscopic cleaning using a suction method. Scientific findings gathered over four years are presented supporting the efficacy and usefulness of this system, the Endo-Suction Cleaning System, also known as the PSK System.

Purpose of the Study: Drainage of the operative wound following total hip or knee replacement (THR, TKR) is usually performed to avoid hematoma formation. A certain amount of blood is lost through the drain. The necessity of wound drainage has been questioned, with a view towards blood saving, although most surgeons have not abandoned drainage for fear of local complications. A prospective randomized study was undertaken to compare drainage and non-drainage following THR/TKR in terms of blood-saving and local complications., Material and Methods: A total of 256 patients undergoing primary THR (152) or TKR (104) were randomly allocated to undergo either suction drainage or no drainage of the wound: there were 76 drained and 76 non-drained THR's, 52 drained and 52 non-drained TKR's. Blood loss was calculated in each patient from the postoperative drop in hematocrit values; the amounts of blood lost intra-operatively and in the drain were also recorded, as was the number of blood units transfused in each patient. Swelling, hip or knee range of motion and wound healing were monitored over the first 6 weeks after operation, and any local or systemic complication was recorded., Results: No significant difference was noted between drained and non-drained THR's/TKR's regarding swelling, recovery of hip or knee motion, wound healing, other local or systemic complications. Following THR, no significant difference was noted between calculated blood losses or transfusion requirements in drained versus non-drained patients. Patients with drains lost on average 1 942 ml of blood versus 1 766 ml for non-drained patients; they received on average 1.18 units of transfused blood versus 1.32 units for patients without drains. The differences are not significant. Following TKR, total blood loss was significantly higher in non-drained than in drained patients (1 983 ml versus 1 590 ml) and the amount of blood transfused was also significantly higher in non-drained patients (0.98 unit versus 0.54 unit)., Conclusion: Following primary hip or knee arthroplasty, the use of wound drainage did not lead to increased blood loss, and non-drainage did not lead to significant wound healing problems but did not reduce blood loss and transfusion requirements. It was even associated, following TKR, with greater blood loss and transfusion. Such data may therefore be used to support drainage as well as non-drainage following THR or TKR. Avoiding drainage may be interesting in terms of cost, but the benefit is marginal; it also eliminates one possible source of retrograde wound infection. Systematic wound drainage following THR or TKR is essentially a tradition. This study shows that it can safely be dispensed with in a number of cases.
