The pediatric PLMA and TT have comparable ventilatory efficacy for elective short laparoscopic procedures.

SummaryMagnesium sulphate is used extensively in the treatment of eclampsia, and is also used to treat refractory arrhythmias, asthma, myocardial ischaemia and acute respiratory failure. We studied the interaction between magnesium sulphate and the anaesthetic agents propofol, rocuronium bromide and fentanyl citrate. This randomised, double blind study was conducted in 50 patients. The magnesium group A (n = 25) received 30 mg.kg )1 magnesium sulphate before induction of anaesthesia and 10 mg.kg )1 continuously intra-operatively until the end of surgery. Group B (n = 25) received the same volume of isotonic saline. Propofol, rocuronium and fentanyl infusions were started and the patients lungs' were ventilated with 33% oxygen in nitrous oxide. Anaesthetic depth was maintained at a bispectral index value of between 40 and 60. Muscle relaxation was maintained at a train-of-four count of 1 throughout surgery using neuromuscular monitoring. The fentanyl infusion was titrated to haemodynamic variables: heart rate and blood pressure. We concluded that magnesium sulphate has anaesthetic, analgesic and muscle relaxation effects and significantly reduces the drug requirements of propofol, rocuronium and fentanyl during anaesthesia.

Thoracoscopic decortication of advanced tuberculous empyema is feasible, safe, and effective with good short- and long-term results in selected patients. In a substantial portion of patients, operative cultures required modifying drug treatment to treat underlying tuberculosis.

Our study in a multicenter setting proves the consistently better performance of automated anesthesia drug delivery compared with conventional manual control. This highlights an important advantage of an automated system for delivering standardized anesthesia, thereby overcoming differences in practices among anesthesiologists.

Background:Optimal pain treatment with minimal side effects is essential for early mobility and recovery in patients undergoing total knee arthroplasty (TKA). We investigated the effect of pregabalin as an adjuvant for postoperative analgesia provided by opioid-based patient-controlled epidural analgesia (PCEA) in such patients.Materials and Methods:Forty patients undergoing unilateral primary TKA were randomly assigned to two equal groups, to receive either placebo or pregabalin 75 mg twice a day. The drug was administered orally starting before surgery and was continued for 2 days after surgery. Anesthetic technique was standardized. Postoperatively, static and dynamic pain was assessed by verbal rating score. Mean morphine consumption, PCEA usage, rescue analgesic requirement, and overall patient satisfaction were also assessed. Treatment emergent adverse drug reactions were recorded.Results:Mean morphine consumption was significantly reduced by pregabalin. Postoperative pain (both static and dynamic) and PCEA consumption too was significantly reduced in the pregabalin group during the first 48 h after surgery. This group needed fewer rescue analgesics and recorded higher overall patient satisfaction. Pregabalin-treated patients had fewer opioid-related adverse reactions like nausea, vomiting, and constipation. Dizziness was noted in two of the patients receiving pregabalin. There was no statically significant difference in the incidence of sedation in the two groups.Conclusions:Oral pregabalin 75 mg started preoperatively is a useful adjunct to epidural analgesia following TKA. It reduces opioid consumption, improves postoperative analgesia, and yields higher patient satisfaction levels.

Context:Morbidly obese patients are prone for intraoperative hemodynamic disturbances and postoperative airway complications.Aim:Comparison of intraoperative hemodynamics and postoperative recovery characteristics of desflurane versus sevoflurane in morbidly obese patients undergoing laparoscopic bariatric surgery.Settings and Design:Randomized controlled trialMaterials and Methods:After institutional ethics committee approval and written informed consent, 40 morbidly obese patients (BMI > 35 kg/m2) were randomized to receive desflurane or sevoflurane as part of a standardized general anesthesia technique. Volatile anesthetic concentration was titrated to maintain electroencephalographic bispectral index score (BIS) in the range of 40-60. Mean arterial pressure (MAP) and heart rate (HR) were recorded preoperatively, at induction and intubation, then at regular intervals. After extubation, early recovery was recorded by time to emergence and orientation to time and place. In post anesthesia care unit, intermediate recovery was assessed by modified Aldrete Score and Digit Symbol Substitution Test (DSST).Results:Intraoperative MAP and HR did not differ between the two groups (P > 0.05). The time to response to painful stimuli, obeying verbal commands and spontaneous eye opening was shorter (P = 0.001) and modified Aldrete Score was higher after desflurane anesthesia than after sevoflurane anesthesia (P = 0.049). DSST also returned towards normal faster after desflurane (28.50 ± 6.30 min vs. 35.0 ± 5.62 min, P = 0.03).Conclusions:Both desflurane and sevoflurane produce similar hemodynamic changes but the immediate and intermediate recovery was significantly faster after desflurane thus contributing to fast tracking and early discharge of patients.
