Electrical acustimulation is comparable to ondansetron in prevention of PONV during and after cesarean delivery under spinal anesthesia and in improving patient satisfaction.

To compare the outcomes of thoracic epidural block with thoracic paravertebral block for thoracotomy in pediatric patients. A prospective double-blind study. 60 pediatric patients aged 1-24 months, ASA II, III scheduled for thoracotomy were randomly allocated into two groups. After induction of general anesthesia, thoracic epidural catheter was inserted in group E (epidural) patients and thoracic paravertebral catheter was inserted in group P (paravertebral) patients. Post operative pain score was recorded hourly for 24 hours. Plasma cortisol level was recorded at three time points. Tidal breathing analysis was done preoperatively and 6 hours postoperatively. Analgesia, serum cortisol level, and pulmonary function parameters were comparable in the two groups. However, failure rate (incorrect placement of catheter) was significantly higher in epidural group than in paravertebral group (7% versus 0%, respectively). The complications were also significantly higher in epidural group (vomiting 14.8%, urine retention 11.1% and hypotension 14.8%) than paravertebral group (0%, 0%, and 3.6%, respectively). We conclude that both thoracic paravertebral block and thoracic epidural block results in comparable pain score and pulmonary function after thoracotomy in pediatric patients; the paravertebral block is associated with significantly less failure rate and side effects.

Background:Thoracic epidural anesthesia (TEA) improves analgesia and outcomes after a cardiac surgery. As aging is a risk factor for postoperative pulmonary complications, TEA is of particular importance in elderly patients undergoing coronary artery bypass graft (CABG).Methods:Fifty patients aged 65–75 years; ASA II and III scheduled for elective CABG were included in the study. Patients were randomized to receive either general anesthesia (GA) group alone or GA combined with TEA group. Heart rate (HR), mean arterial pressure (MAP), and central venous pressure were recorded. Total dose of fentanyl μg/kg, aortic cross clamping, cardiopulmonary bypass (CPB) time, time to first awaking and extubation, arterial blood gases, visual analog scale (VAS) score in intensive care unit were reported. Postoperative pulmonary function tests were done.Results:TEA showed a significant HR and lower MAP compared with the GA group. The total dose of intraoperative fentanyl and nitroglycerine were significantly lower in the TEA. Patients in TEA group have statistically significantly higher PaO2, lower PaCO2, increase in Forced Vital Capacity (FVC) and Forced Expiratory Volume in one second (FEV1)Conclusions:TEA reduced severity of postoperative pulmonary function and restoration was faster in TEA group in elderly patients undergoing CABG. Also, it resulted in earlier extubation and awakening, better analgesia, lower VAS.
