Background and Aims: The safety of subarachnoid block (SAB) was established in preeclamptic parturients, but most of studies are of low quality. The study aimed to compare the hemodynamic parameters, phenylephrine requirement, and the neonatal outcome between normotensive and preeclamptic parturients undergoing cesarean section. Methods: This prospective observational study was conducted in 100 parturients, aged between 18 and 35 years, American Society of Anesthesiologists II/III scheduled for elective cesarean section under SAB. The heart rate, systolic blood pressure (SBP), diastolic blood pressure (DBP), and mean blood pressure (MBP) were recorded at the baseline, before SAB, and every 2 min till 30 min and then every 5 min till the end of the surgery. Phenylephrine was administered in a bolus of 50 μg when the MBP falls by 20% from the baseline. Neonatal outcomes were measured with the umbilical artery pH and APGAR scores at 1 and 5 min. The Statistical Package for the Social Science (SPSS) 26 was used for analysis. Results: The percentage fall in DBP and mean arterial BP from baseline was statistically significant between groups (26.83% ± 9.58% vs. 20.06% ± 14.17% and 24.90% ± 6.49% vs. 20.11% ± 9.75%). The mean requirement of phenylephrine was higher in the normotensive group than the preeclamptic (95.16 ± 41.54, 68.42 ± 31.14) (P < 0.001). The umbilical artery pH and APGAR scores at 1 and 5 min were comparable in both the groups. Conclusion: The incidence of hypotension was less in preeclamptic and required less phenylephrine compared to normotensives, with comparable neonatal parameters in parturients undergoing cesarean section under spinal anesthesia.

Abstract Background Dexamethasone is used in regional analgesia to prolong the duration of analgesia and anaesthesia. The perineural and intravenous (IV) dexamethasone in fascial plane block have conflicting results. The study aimed to compare analgesic efficacy of perineurally and intravenously dexamethasone in rectus sheath block (RSB). This prospective, double-blinded, randomized control study was conducted in 105 patients, equally divided in three groups. All the patients received ultrasound-guided RSB block with 20 ml of 0.25% levobupivacaine on each side. Additionally, in group A, 1-ml normal saline (NS) on each side in RSB block and 2-ml NS IV; in group B, 4-mg dexamethasone on each side in RSB block and 2-ml NS IV; and in group C, 1-ml NS on each side in RSB block and 8-mg dexamethasone IV. The primary objective of the study was the duration of analgesia, and secondary objectives were total morphine consumption in the first 24 h, numeric rating scale (NRS) scores at rest and on cough, complications and patient’s satisfaction score. Results The duration of analgesia was maximum in group B (935.91 ± 121.82 min) and then in group C (730.31 ± 129.64 min) and group A (418.34 ± 29.22 min) (P

Background and Aim: Pneumoperitoneum (PP) and the Trendelenburg position (TP) in laparoscopic surgeries are associated with rise in intracranial pressure (ICP). The optic nerve sheath diameter (ONSD) is a surrogate marker of ICP. The study aimed to evaluate the effect of sevoflurane, propofol and propofol with dexmedetomidine as maintenance agent on ICP in TP during laparoscopic surgeries. Material and Methods: A total of 120 American Society of Anesthesiologists (ASA) physical status I/II patients, aged 18–65 years were randomly allocated into three groups: sevoflurane as group S, propofol as group P, and propofol with dexmedetomidine as group PD. The intra-abdominal pressure (IAP) was kept in the range of 12–14 mmHg and TP varied between 15°– 45° angle. The primary objective was comparison of ICP and secondary objectives were IOP, intraoperative hemodynamic and postoperative recovery characteristics among groups. The ONSD and IOP were measured in both eyes 10 min after endotracheal intubation (T0), 5 min after CO2 insufflation (T1), 5 min after TP (T2) and 5 min after deflation of gas (T3). The data were analyzed by using the Statistical Package for Social Sciences version 23. Results: ONSD and IOP at T1 and T2 were significantly higher than T0 in all groups, but no significant difference was found among the intergroup groups. Significantly lower heart rate and mean blood pressure were observed in PD group at T1 and T2 compared to group S and group P. Conclusion: The rise in ICP was comparable among sevoflurane, propofol, and propofol–dexmedetomidine combination as a maintenance agent during laparoscopic surgeries in TP.

Recent development in science has led to a significant improvement in safety for the anaesthetic management of children. Enhanced recovery after surgery is one of the novel approaches aiming to enhance paediatric surgical outcomes and their quick recovery. Preoperative counselling, minimal fasting, and no routine pharmacological premedication are critical components of enhanced recovery after surgery. As anaesthetists, management of airway is our priority and introduction of paraoxygenation in addition to preoxygenation has resulted in reduction in desaturation episodes during periods of apnoea. Safe care has been made possible by improvements in monitoring, equipment, medications, techniques, and resuscitation protocols. We are motivated to collect more evidence regarding ongoing disputes and issues, such as the effect of anaesthesia on neurodevelopment.

Background: The COVID-19 has a varied mode of presentation in different regions of the world. This multicentric study was planned to evaluate the survival outcomes in intensive care unit-admitted patients admitted during the third wave of the COVID-19 pandemic on the basis of clinicodemographic profile and vaccination status. Methodology: Data from 299 patients admitted to three tertiary care centers in Western India were collected and analyzed. Based on survival outcomes, all patients were divided into two groups: survivors and nonsurvivors. Univariate analysis of the demographic profile, comorbidities, vaccination status, and disease severity was performed, whereas multivariate analysis was performed to predict independent factors associated with mortality. Results: Among total 299 studied patients, 208 (69.5%) patients survived and 91 (30.4%) did not. The number of elderly patients and patients with comorbidities such as diabetes, tuberculosis, chronic obstructive pulmonary disease, cardiovascular and respiratory diseases, and malignancy were more prevalent among nonsurvivors. Patients who did not receive a single dose of vaccine were higher in the nonsurvivor group (P = 0.037); however, no significant difference in survival outcome was found if patients had received the first or both doses of vaccine. The Acute Physiology and Chronic Health Evaluation II (APACHE II) score at 24 h after admission and Sequential Organ Failure Assessment (SOFA) score at admission were significantly higher in nonsurvivors compared to survivors (P < 0.0001). On multivariate analysis, APACHE II and SOFA scores were found to be independent predictors of outcome. Conclusions: Older age, presence of comorbidities, nonvaccination and higher disease severity scores affected mortality during the third wave of COVID-19.

Background Supraglottic airways (SGA) are increasingly used in pediatric anesthesia. Among SGA, I-gelTM is a commonly used device in pediatric patients. The BlockbusterTM laryngeal mask airway (LMA) is latest addition in pediatric airway armamentarium. This study was conducted to compare the clinical performance of I-gelTM and BlockbusterTM LMA in pediatric patients. Methods A total of 140 children aged 1–5 years, who were undergoing elective surgery, were randomized into two groups either I-gelTM (Group I) or BlockbusterTM LMA (Group B). Airway was secured with appropriate-sized LMA according to group allocation under general anesthesia. The primary objective of study was oropharyngeal leak pressures (OPLP), and secondary objectives were number of attempts of device insertion, success rate, ease of LMA insertion, hemodynamic parameters, and postoperative pharyngolaryngeal morbidities. Results The mean OPLP was significantly higher for I-gelTM compared to BlockbusterTM LMA (27.97 ± 1.65 vs. 26.04 ± 2.12; P < 0.001). The devices were successfully inserted on the first attempt in 97.14% and 90% of the Group I and Group B respectively. The insertion time, ease of insertion, hemodynamic parameters and postoperative complications were comparable between groups. Conclusions The I-gelTM was more efficacious device in term of OPLP than BlockbusterTM LMA for positive pressure ventilation in pediatric patients undergoing short surgical procedures under general anesthesia.

Background Allaying anxiety and providing calm children in the operating room is a challenging task for anesthesiologists. This study was designed to compare the use of nebulized dexmedetomidine and ketamine for premedication in pediatric patients under general anesthesia. Methods Seventy patients, aged 2 to 8 years of both sexes, with American Society of Anesthesiologists physical status I/II scheduled for hernia repair surgery under general anesthesia, were randomized to two equal groups using a computer-generated random number table. Patients in group D received dexmedetomidine (2 µg/kg), and patients in group K received ketamine (2 mg/kg) by a jet nebulizer before the induction of anesthesia. The study's primary objective was comparing the level of sedation, which was achieved at 30 min after a study drug administration using the Ramsay sedation scale, between the two groups. The secondary objectives were the two-group comparison of parental separation anxiety scale, acceptance of the mask, hemodynamic variables, recovery time, incidence of emergence agitation, and adverse events. Results The median Ramsay sedation scale at 30 min was 3 (1–4) in group D and 3 (1–3) in group K (P = 0.002). Patients in group D had a more acceptable parental separation anxiety scale (P = 0.001) and a satisfactory mask acceptance scale (P = 0.042). Conclusions Nebulized dexmedetomidine (2 µg/kg) provided better sedation along with smooth parental separation and satisfactory mask acceptance during induction of anesthesia with a similar emergence agitation profile and adverse reactions compared to nebulized ketamine in pediatric patients.

Background Epidural block placement in pediatric patients is technically challenging for anesthesiologists. The use of ultrasound (US) for the placement of an epidural catheter has shown promise. We compared landmark-guided and US-guided lumbar or lower thoracic epidural needle placement in pediatric patients. Methods This prospective, randomized, comparative trial involved children aged 1–6 years who underwent abdominal and thoracic surgeries. Forty-five children were randomly divided into two groups using a computer-generated random number table, and group allocation was performed by the sealed opaque method into either landmark-guided (group LT) or real-time ultrasound-guided (group UT) epidural placement. The primary outcome was a comparison of the procedure time (excluding US probe preparation). Secondary outcomes were the number of attempts (re-insertion of the needle), bone contacts, needle redirection, skin-to-epidural distance using the US in both groups, success rate, and complications. Results The median (interquartile range) time to reach epidural space was 105.5 (297.0) seconds in group LT and 143.0 (150) seconds in group UT (P = 0.407). While the first attempt success rate was higher in the UT group (87.0% in UT vs. 40.9% in LT; P = 0.004), the number of bone contacts, needle redirections, and procedure-related complications were significantly lower. Conclusions The use of US significantly reduced needle redirection, number of attempts, bone contact, and complications. There was no statistically significant difference in the time to access the epidural space between the US and landmark technique groups.

Background and Aims: Preservative free 1% 2-chlorprocaine is a short acting local anaesthetic agent suitable for day care surgical procedures. Potentiation of analgesic action of intrathecal local anaesthetics by the addition of opioids is well known. In this study, we investigated the effect of intrathecal fentanyl as an adjuvant to 1% 2-chloroprocaine (2-CP) in parturients undergoing elective lower segment caesarean section (LSCS). Methods: This prospective randomised comparative study was performed on 150 healthy, term parturients planned for elective low risk LSCS, divided into two equal groups. The group CS received 1% preservative-free 2-CP 3 ml (30 mg) + 0.5 ml normal saline and group CF received 1% preservative-free 2-CP 3 ml (30 mg) + 0.5 ml fentanyl (25 μg) with a total volume of 3.5 ml intrathecally in both groups. The duration of sensory blockade, duration of motor blockade, maximum height of sensory block, haemodynamic parameters, quality of block, neonatal outcome, patient satisfaction and any side effects were recorded. Results: There were no significant differences in demographic characteristics, haemodynamic parameters, onset of sensory block, onset of motor block and duration of motor block between the groups. The duration of sensory block and duration of analgesia was statistically prolonged in group CF than group CS (P value < 0.0001). There was no statistical difference in the Apgar score of newborns in both groups. The adverse effects (hypotension, bradycardia, nausea/vomiting, shivering and transient neurological symptoms) were comparable in both the groups. Conclusion: The addition of fentanyl to 1% 2-chloroprocaine intrathecally prolonged the duration of sensory block and postoperative analgesia in patients undergoing LSCS.

Background and Aims: Coronary artery bypass grafting (CABG) surgery involves various noxious stimuli resulting in stress response, which in turn increases the risk of perioperative myocardial ischemia. The present study was conducted to evaluate the effect of dexmedetomidine on the attenuation of hemodynamic response to intubation, skin incision, and sternotomy in CABG surgery. Material and Methods: Sixty patients were randomized into two groups of 30 each. Group D patients received dexmedetomidine 1 μg/kg as loading dose over 10 min, followed by continuous infusion of 0.5 μg/kg/h. In group P, normal saline was infused as loading and maintenance dose at similar rate. Hemodynamic parameters, total induction dose of thiopentone, and adverse effects were recorded. Statistical analysis was performed using SPSS version 20.0. Chi-square test and ANNOVA test were used and P < 0.05 was considered significant. Results: The percentage increase in heart rate was significantly lesser in group D than group P after intubation (7.04% v/s 15.08%), skin incision (5.91% v/s 10.11%), and sternotomy (5.33% v/s 11.65%). Similarly increase in systolic, diastolic, and mean blood pressure were significantly lesser in group D than group P after intubation, skin incision, and sternotomy. There was a significant reduction of mean total of thiopentone in group D in comparison to group P. (1.16 mg/kg v/s 2.44 mg/kg) (P< 0.001). Conclusion: Dexmedetomidine resulted in significant attenuation of hemodynamic response to intubation, skin incision, and sternotomy in CABG surgery without significant adverse effects. It also significantly reduced the dose of thiopentone required for induction.

Background: Quadratus lumborum block (QLB) provides somatic and visceral analgesia to the lower thoracic and abdominal wall. The aim was to investigate the analgesic effect of dexamethasone with levobupivacaine in QLB in patients undergoing unilateral inguinal hernia repair surgery. Methods: A total of 90 patients of American Society of Anaesthesiologists (ASA) I/II were randomly divided into two groups. Group L received 0.25% levobupivacaine (20 ml) + normal saline (1 ml) and group D received 0.25% levobupivacaine (20 ml) + 4 mg dexamethasone (1 ml) in QL plane on the operated side using ultrasound, after completion of surgery under spinal anaesthesia. The primary objective was to compare time for first rescue analgesia. The secondary objectives were total rescue analgesic consumption and numeric rating scale (NRS) in the first 24 h. Results: The demographic data age, sex, height, weight and ASA were comparable in both groups. The mean time to request for first rescue analgesia was longer in group D compared to group L (1016.02 ± 205.97 min versus 640 ± 132.96 min; P < 0.0001). The mean total tramadol consumption in the first 24 h was lower in group D compared to group L (233.55 ± 86.92 mg versus 328.22 ± 78.74 mg; P < 0.0001). Patients in group D had significantly lower NRS scores at rest and on movement as compared to group L. Conclusions: The addition of dexamethasone to levobupivacaine in QLB results in prolonged duration of postoperative analgesia, less rescue analgesic requirements and better quality of analgesia as compared to levobupivacaine in unilateral inguinal hernia repair surgery.

Background and Aim: The anaesthesiologists are at the highest risk of contracting infection of coronavirus disease 2019 (COVID-19) in emergency room, operation theatres and intensive care units. This overwhelming situation can make them prone for psychological stress leading to anxiety and insomnia. Materials and Methods We did an online self-administered questionnaire-based observational cross-sectional study amongst anaesthesiologists across India. The objectives were to find out the main causes for anxiety and insomnia in COVID-19 pandemic. Generalised Anxiety Disorder-7 (GAD-7) scale and Insomnia Severity Index (ISI) were used for assessing anxiety and insomnia. Results: Of 512 participants, 74.2% suffered from anxiety and 60.5% suffered from insomnia. The age

Background The transversus abdominis plane (TAP) block is an effective technique to block the thoracolumbar nerves innervating the anterolateral abdominal wall. This study was conducted to evaluate the analgesic efficacy and opioid consumption with the use of perineural buprenorphine or dexamethasone in TAP blocks after unilateral inguinal hernioplasties. Methods This prospective, randomized, double-blinded, placebo-controlled study enrolled 93 patients scheduled for unilateral inguinal hernioplasty, followed by an ultrasound-guided TAP block. The participants were randomized into 3 groups (31 patients each). Group L received 20 ml 0.25% levobupivacaine + 1 ml normal saline (NS); group LB, 20 ml 0.25% levobupivacaine + 0.3 mg (1 ml) buprenorphine; and group LD, 20 ml 0.25% levobupivacaine + 4 mg (1 ml) dexamethasone. The patients were observed postoperatively for 24 h for first rescue analgesic requirement, total rescue analgesic consumption, and pain scores on the numeric rating scale (NRS). Results The time to first rescue analgesic requirement was significantly longer in Group LB than in groups LD and L (688.87 ± 36.11 min, 601.45 ± 39.85 min, and 383.06 ± 36.21 min, respectively; P < 0.001). The mean total tramadol consumption in the first 24 h was the lowest in group LB (P < 0.001, L vs. LB / LD). Groups LB and LD displayed significantly lower NRS scores than group L (P < 0.001 both). Conclusions Levobupivacaine with perineural buprenorphine in a TAP block after unilateral open inguinal hernioplasty facilitates prolonged analgesia and reduced requirement for rescue analgesics compared to perineural dexamethasone, without significant side effects.

Background and Aims: Pectoral nerve (PecS II) block is the latest modality for providing postoperative analgesia after breast surgery. The present study was planned to compare the analgesic efficacy of thoracic paravertebral block (TPVB) and PecS II for postoperative analgesia after modified radical mastectomy (MRM). Methods: A total of 40 female patients undergoing radical mastectomy were randomly allocated into two groups (n = 20). Group T received ultrasound-guided TPVB, while group P received PecS II block using 0.25% levobupivacaine 24 ml + dexamethasone 1 ml (4 mg) before induction of anesthesia. The primary outcome was duration of analgesia (time to request first analgesic dose), while total rescue analgesic consumption in first 24 h, numeric rating score (NRS), and complication were secondary outcomes. The data were analyzed using IBM SPSS software version 22.0. Results: The duration of analgesia was significantly prolonged in the group P than group T (474.1 ± 84.93 versus 371.5 ± 51.53 min, respectively; P < 0.0001). Postoperative morphine consumed at 24 h was less in the group P than group T (11.25 ± 4.75 and 15.0 ± 4.86 mg, respectively; P = 0.018). NRS at movement and rest were lower in the group P as compared to group T at all time intervals (median 3 versus 4). No block-related complication was recorded in any group. Conclusions: The 0.25% levobupivacaine with dexamethasone 4 mg in PecS II block provided longer duration of analgesia than the TPVB in patients undergoing MRM without any adverse effects.

Background and Aims: Postoperative pain results in prolonged hospital stay and delayed return to normal activity. This study was conducted with the aim of evaluating the analgesic efficacy of gelfoam soaked in levobupivacaine with or without dexamethasone placed in the epidural space in patients undergoing lumbar laminectomy. Methods: Ninety adult patients were randomised into three groups. Gelfoam was soaked in 12 mL of 0.9% sodium chloride in Group P, 10 mL of 0.25% levobupivacaine + 2 mL of 0.9% sodium chloride in Group L, and 10 mL of 0.25% levobupivacaine + 2 mL of dexamethasone in group LD. The primary outcome was time to first request for rescue analgesia. Total 24-h tramadol consumption, and postoperative visual analog scale (VAS) scores were recorded. Chi-square test and analysis of variance test were used, and P < 0.05 was considered significant. Results: 75 patients completed the study. Time to first rescue analgesia was longer in group LD [10.11 ± 3.10 h] compared with group L [6.48 ± 2.36 h] and group P [1.76 ± 1.13 h]. Total 24-h tramadol consumption was lower in group LD (88 ± 66.58 mg) and group L (120 ± 70.7 mg) compared with group P (280 ± 64.5 mg). Postoperative VAS scores were lower in group LD and group L compared with group P, both at rest and on movement. Conclusion: Epidural gelfoam soaked in levobupivacaine and dexamethasone prolongs the duration of analgesia and decreases rescue analgesic consumption and VAS score postoperatively, in patients undergoing lumbar laminectomy.

Background and Aims: Nasal surgery under desflurane anaesthesia is more prone to develop emergence agitation (EA). The present study aimed to evaluate the efficacy of dexmedetomidine for prevention of EA. Methods: A total of 72 patients were randomised to group C and group D. Group C patients received placebo while group D patients received dexmedetomidine 1.0 μg/kg bolus followed by 0.4 μg/kg/h after induction of anesthesia. End tidal desflurane was adjusted to keep the bispectral index (BIS) 45–55. Study drug was stopped at extubation. EA was evaluated from extubation till the patient was shifted to postanaesthesia care unit (PACU). Primary outcome was incidence of EA. Secondary outcome measures were requirement of desflurane, haemodynamic stability, and recovery after anaesthesia. The results were analyzed using SPSS version 21. Results: Infusion of dexmedetomidine significantly reduced the incidence of EA (Group C 52.8%; Group D 5.6%) by 89.5% (P = 0.00001). The endtidal desflurane concentration was significantly lower and there was an average 28.87% reduction in requirement of desflurane in group D compared to group C (P < 0.001). The mean heart rate was significantly higher in Group C (P < 0.001). In group C time to extubation, time to achieve BIS 90 and time to response on verbal command was significantly lesser compared to group D (P < 0.0001). Conclusion: Dexmedetomidine significantly reduced the incidence of EA and requirement of desflurane in patients undergoing nasal surgery. However, it was associated with delayed extubation, residual sedation, and prolonged PACU stay.

Patients with Patau's syndrome (Trisomy 13) have multiple craniofacial, cardiac, neurological and renal anomalies with very less life expectancy. Among craniofacial anomalies cleft lip and palate are common. These craniofacial and cardiac anomalies present difficulties with anesthesia. We therefore describe the anesthetic management in the case of a Trisomy 13 child for operated for cleft lip at 10 months of age. Resumo: Os pacientes com síndrome de Patau (trissomia 13) apresentam várias anomalias craniofaciais, cardíacas, neurológicas e renais, com expectativa de vida bem menor. Entre as anomalias craniofaciais, o lábio leporino e a fenda palatina são comuns. Essas anomalias craniofaciais e cardíacas apresentam dificuldades na anestesia. Portanto, descrevemos o manejo anestésico em uma criança de 10 meses de idade com Trissomia 13 submetida à cirurgia de lábio leporino.

Context: Caudal analgesia is a reliable and an easy method to provide intraoperative and postoperative analgesia for infraumbilical surgeries in pediatric population but with the disadvantage of short duration of action after single injection. Many additives were used in combination with local anesthetics in the caudal block to prolong the postoperative analgesia. Aim: We compared the analgesic effects and side effects of dexmedetomidine added to ropivacaine in pediatric patients undergoing lower abdominal surgeries. Settings and Design: Double-blinded randomized controlled trial. Materials and Methods: Sixty patients (2-10 years) were evenly and randomly assigned into two groups in a double-blinded manner. After sevoflurane in oxygen anesthesia, each patient received a single caudal dose of ropivacaine 0.25% (1 ml/kg) combined with either dexmedetomidine 2 μg/kg in normal saline 0.5 ml, or corresponding volume of normal saline according to group assignment. Hemodynamic variables, end-tidal sevoflurane, and emergence time were monitored. Postoperative analgesia, requirement of additional analgesic, sedation, and side effects were assessed during the first 24 h. Results: The duration of postoperative analgesia was significantly longer (P = 0.001) and total consumption of rescue analgesic was significantly lower in Group RD compared with Group R (P < 0.05). Group RD have better quality of sleep and prolonged duration of sedation (P = 0.001). No significant difference was observed in the incidence of hemodynamic changes or side effects. Conclusion: Addition of dexmedetomidine to caudal ropivacaine significantly prolongs analgesia in children undergoing lower abdominal surgeries without an increase in the incidence of side effects.

Introduction: Percutaneous Nephrolithotomy (PCNL) is the treatment modality used for the extraction of large renal stones, or multiple calculi or stones resistant to shock wave lithotripsy. The General Anaesthesia (GA) is the standard modality for PCNL. However, few studies conclude that Spinal Anaesthesia (SA) can be an alternative method of anaesthesia with similar incidence of complications. Aim: In our study we evaluated the feasibility of spinal anaesthesia in terms of intraoperative and postoperative results in patients undergoing PCNL. Materials and Methods: The total 1298 PCNL operations were done for kidney stone from January 2013 to December 2016, out of which 1160 patients underwent PCNL under SA while remaining 138 operations were carried out under GA in the prone position. We retrospectively collected data from the patient’s documents. The intraoperative haemodynamic stability was primary objective, and average fall of haemoglobin, postoperative anaesthetic outcome like total tramadol used in first 24 hours, surgical outcome like total clearance of stone burden, patient satisfaction, surgeon satisfaction, need of blood transfusion, conversion to general anaesthesia and pleural puncture were the secondary objectives. Results: The mean age of the patients was 38.0±17.1 years, and the mean operative time was 80.0±25.9 minutes. The mean calculus size was 30.2±11.8 mm. Return of sensory and motor activity took 150.0±29.2 minutes and 111.0±18.8 minutes, respectively. In first 10 minutes of anaesthesia, 148 (12.75%) patients developed hypotension, which was managed by ephedrine 6 mg intravenously (IV). Total seventy two patients (6.2%) needed blood transfusion and 32 (2.75%) complained of headache, dizziness and low back pain for two to four days after the operation, which improved with analgesics and bed rest. Ninety percent of the patients had complete clearance of calculus or there were no significant residual calculi larger than 5 mm on follow up ultrasonography. Conclusion: It can be concluded from our study that spinal anaesthesia is the safe and effective method of anaesthesia for PCNL in adult patients.

Introduction: As Laparoscopic Cholecystectomy (LC) is not a totally pain free procedure, with the pain being most intense on the day of surgery and on the following day. Various techniques are available for postoperative pain relief like intraperitoneal instillation of local anaesthetics and rectus sheath block (RSB) which may provide effective pain relief. Aim: To compare the efficacy of preemptive administration (initiated before the surgical procedure) of intraperitoneal instillation and rectus sheath block using ropivacaine for postoperative analgesia after laparoscopic cholecystectomy. Materials and Methods: A total of 75 selected patients were randomly assigned to three equal groups as Group R, who received bilateral RSB with 0.25 % ropivacaine 15 ml on either side; Group I, who received intraperitoneal instillation of 0.25% ropivacaine 50 ml and Group C (Control group), who received only rescue analgesic on pain. These were compared regarding postoperative analgesia in terms of Visual Analog Scale (0-10 cm), Prince Henry Hospital Pain Score (0-3), time to first dose of rescue analgesic (tramadol), total rescue analgesic consumption in 48 hours, patient satisfaction scores (1-7) and adverse effects. Results: The time to first rescue analgesic was significantly longer in Group R (16.16±4.73h) and Group I (7.84±1.34h) as compared to Group C (1.72±0.67h), p Group I > Group C. Rescue analgesic requirement showed a 32.21% reduction in Group I and 50.33% reduction in Group R as compared to Group C. Patient Satisfaction Scores (PSS) showed a significant difference among groups with acceptable PSS scores as: Group R (92%) v/s Group I (40%) v/s Group C (20%) p

Background and Aim: Sedation plays a pivotal role in the care of the critically ill patient. It is equally important to assess depth of sedation. The present study had been designed to compare dexmedetomidine and propofol for sedation in mechanically ventilated intensive care patients. It also intended to verify the clinical validity, reliability and applicability of objective assessment tool bispectral index (BIS) for monitoring sedation and observe for correlation with the commonly used subjective scale, Ramsay sedation score (RSS). Materials and Methods: This prospective randomized study was carried out in 60 haemodynamically stable patients, aged between 18 to 80 years, requiring sedation and mechanical ventilation. These were divided equally into two groups. Group A received dexmedetomidine loading dose (1μg/kg) over 10 min followed by maintenance infusion of 0.5μg/kg/hr (0.2-0.7 μg/kg/hr). Group B received propofol loading dose (1mg/kg) over 5 min followed by infusion of 2mg/kg/hr (1-3mg/kg/hr). All patients received fentanyl 1 μg/kg prior to the study drugs. Vital parameters and sedation levels (using RSS and BIS) were monitored for the study period of 12 hours with level 4 or 5 of RSS as target for sedation. Ramsay score was compared with the average of BIS values. Statistical analysis was done using SPSS VERSION 17 software. Results: The study revealed statistically significant lower heart rates during sedation in dexmedetomidine group whereas fall in mean arterial pressure (MAP) following loading dose in propofol group. Patients sedated with dexmedetomidine were easily arousable. Need for rescue drug for achieving the desired RSS as well as incidence of bradycardia was more in dexmedetomidine group than other. Good correlation exists between Ramsay score and BIS values. Conclusion: Dexmedetomidine reduces heart rate while propofol transiently affects MAP. However, adequate sedation is achieved with both the drugs. The data obtained from the study validate BIS monitoring for ICU sedation.
