Background: Variability in obstetric outcomes in terms of the number and type of deliveries related to the day–night cycle has been described in previous studies. This 11-year retrospective analysis explores the effects of nighttime versus daytime delivery with labor epidural on obstetric outcomes. Methods: Data on deliveries performed between 1 October 2008 and 1 October 2019 were collected and differentiated into daytime, occurring from 8:00 a.m. to 7:59 p.m., and nighttime deliveries, occurring from 8:00 p.m. to 7:59 a.m. of the following day. The data collected included the patient history and maternal and neonatal outcomes. Results: A total of 29831 patients were included in the analysis. A positive and statistically significant correlation between the number of cesarean sections (Odds Ratio 1.35; 95% confidence interval = 1.26–1.44; p < 0.001) and the number of vaginal operative deliveries (Odds Ratio 1.21; 95% confidence interval = 1.01–1.44; p < 0.05) in patients who did not receive an epidural at nighttime was reported. Regarding the labor epidurals, a significantly greater incidence of accidental dural punctures with needles (0,4%; p < 0.05) in the nighttime versus daytime was reported. Conclusions: The absence of labor epidurals was associated with a significant increase in the number of cesarean sections and vaginal operative deliveries occurring at nighttime, without significant differences in labor duration. The incidence of anesthesiologic complications was greater in deliveries performed at nighttime. [ABSTRACT FROM AUTHOR]

Background: Intraoperative hypotension is associated with increased perioperative complications, hospital length of stay (LOS) and healthcare expenditure in gynecologic surgery. We tested the hypothesis that the adoption of a machine learning-based warning algorithm (hypotension prediction index—HPI) might yield an economic advantage, with a reduction in adverse outcomes that outweighs the costs for its implementation as a medical device. Methods: A retrospective-matched cohort cost–benefit Italian study in gynecologic surgery was conducted. Sixty-six female patients treated with standard goal-directed therapy (GDT) were matched in a 2:1 ratio with thirty-three patients treated with HPI based on ASA status, diagnosis, procedure, surgical duration and age. Results: The most relevant contributor to medical costs was operating room occupation (46%), followed by hospital stay (30%) and medical devices (15%). Patients in the HPI group had EURO 300 greater outlay for medical devices without major differences in total costs (GDT 5425 (3505, 8127), HPI 5227 (4201, 7023) p = 0.697). A pre-specified subgroup analysis of 50% of patients undergoing laparotomic surgery showed similar medical device costs and total costs, with a non-significant saving of EUR 1000 in the HPI group (GDT 8005 (5961, 9679), HPI 7023 (5227, 11,438), p = 0.945). The hospital LOS and intensive care unit stay were similar in the cohorts and subgroups. Conclusions: Implementation of HPI is associated with a scenario of cost neutrality, with possible economic advantage in high-risk settings. [ABSTRACT FROM AUTHOR]

ESP block (ESPB) and posterior Quadratus Lumborum Block (pQLB) have been proposed as opioid-sparing techniques for the management of pain after abdominal surgery. Between December 2021 and October 2022, we conducted a retrospective comparative study at the delivery suite of Fondazione Policlinico Universitario Agostino Gemelli IRCCS, Rome, Italy, to compare the efficacy of ESPB and pQLB in preventing postoperative pain after an elective caesarean section (CS). The primary outcome was total morphine consumption in the first 24 h. Secondary outcomes were time to first opioid request; Numerical Pain Rating Scale (NPRS) at 0, 2, 6, 12 and 24 h; vital signs; adverse events. Fifty-two women were included. The total cumulative dose of morphine was not significantly different between the two groups of patients (p = 0.897). Time to first dose of morphine, NPRS values and haemodynamic parameters were not statistically different between the two groups. NPRS values significantly increased (p < 0.001) at the different time intervals considered. The need for rescue doses of morphine was lower in the ESPB group compared to the pQLB group (hazard ratio of 0.51, 95% CI (0.27 to 0.95), p = 0.030). No adverse event was reported. ESPB seems to be as effective as pQLB in providing analgesia after CS. [ABSTRACT FROM AUTHOR]

Background: Adequate pain management for abdominal hysterectomy is a key factor to decrease postoperative morbidity, hospital length of stay and chronic pain. General anesthesia is still the most widely used technique for abdominal hysterectomy. The aim of this study was to assess the efficacy and safety of blended anesthesia (spinal and general anesthesia) compared to balanced general anesthesia in patients undergoing hysterectomy with or without lymphadenectomy for ovarian, endometrial or cervical cancer or for fibromatosis. Methods: We retrospectively collected data from adult ASA 1 to 3 patients scheduled for laparoscopic or mini-laparotomic hysterectomy with or without lymphadenectomy for ovarian, endometrial or cervical cancer or for fibromatosis. Exclusion criteria were age below 18 years, ASA > 3, previous chronic use of analgesics, psychiatric disorders, laparotomic surgery with an incision above the belly button and surgery extended to the upper abdomen for the presence of cancer localizations (e.g., liver, spleen or diaphragm surgery). The cohort of patients was retrospectively divided into three groups according to the anesthetic management: general anesthesia and spinal with morphine and local anesthetic (Group 1), general anesthesia and spinal with morphine (Group 2) and general anesthesia without spinal (Group 3). Results: NRS was lower in the spinal anesthesia groups (Groups 1 and 2) than in the general anesthesia group (Group 3) for every time point but at 48 h. The addition of local anesthetics conferred a small but significant NRS decrease (p = 0.009). A higher percentage of patients in Group 3 received intraoperative sufentanil (52.2 ± 18 mcg in Group 3 vs. Group 1 31.8 ± 16.2 mcg, Group 2 44.1 ± 15.6, p < 0.001) and additional techniques for postoperative pain control (11.4% in Group 3 vs. 2.1% in Group 1 and 0.8% in Group 2, p < 0.001). Intraoperative hypotension (MAP < 65 mmHg) lasting more than 5 min was more frequent in patients receiving spinal anesthesia, especially with local anesthetics (Group 1 25.8%, Group 2 14.6%, Group 3 11.6%, p < 0.001), with the resulting increased need for vasopressors. Recovery-room discharge criteria were met earlier in the spinal anesthesia groups than in the general anesthesia group (Group 1 102 ± 44 min, Group 2 91.9 ± 46.5 min, Group 3 126 ± 90.7 min, p < 0.05). No differences were noted in postoperative mobilization or duration of ileus. Conclusions: Intrathecal administration of morphine with or without local anesthetic as a component of blended anesthesia is effective in improving postoperative pain control following laparoscopic or mini-laparotomic hysterectomy, in reducing intraoperative opioid consumption, in decreasing postoperative rescue analgesics consumption and the need for any additional analgesic technique. We recommend managing postoperative pain with a strategy tailored to the patient's physical status and the type of surgery, preventing and treating side effects of pain treatments.

Malignant hyperthermia is a rare but life-threatening pharmacogenetic disorder triggered by exposure to specific anesthetic agents. Although this occurrence could affect virtually any patient during the perioperative time, the pediatric population is particularly vulnerable, and it has a five-fold higher incidence in children compared to adults. In the last few decades, synergistic efforts among leading anesthesiology, pediatrics, and neurology associations have produced new evidence concerning the diagnostic pathway, avoiding unnecessary testing and limiting false diagnoses. However, a personalized approach and an effective prevention policy focused on clearly recognizing the high-risk population, defining perioperative trigger-free hospitalization, and rapid activation of supportive therapy should be improved. Based on epidemiological data, many national scientific societies have produced consistent guidelines, but many misconceptions are common among physicians and healthcare workers. This review shall consider all these aspects and summarize the most recent updates. [ABSTRACT FROM AUTHOR]

Background: Lumbar epidural analgesia (EA) is the most commonly used method for reducing labour pain, but its impact on the duration of the second stage of labour and on neonatal and maternal outcomes remains a matter of debate. Our aim was to examine whether EA affected the course and the outcomes of labour among patients divided according to the Robson-10 group classification system. Methods: Patients of Robson's classes 1, 2a, 3, and 4a were divided into either the EA group or the non-epidural analgesia (NEA) group. A propensity score-matching analysis was performed to balance the intergroup differences. The primary goal was to analyse the duration of the second stage of labour. The secondary goals were to evaluate neonatal and maternal outcomes. Results: In total, 21,808 cases were analysed. The second stage of labour for all groups was prolonged using EA (p < 0.05) without statistically significant differences in neonatal outcomes. EA resulted in a lower rate of episiotomies in nulliparous patients, with a higher rate of operative vaginal deliveries (OVD) (p < 0.05) and Caesarean sections (CS) (p < 0.05) in some classes. Conclusions: EA prolonged the duration of labour without affecting neonatal outcomes and reduced the rate of episiotomies, but also increased the rate of OVDs. [ABSTRACT FROM AUTHOR]
