It is known that, unilateral thoracic paravertebral block (TPVB) applications performed with general anesthesia provide satisfactory conditions for open cholecystectomy increase the quality of post-operative analgesia and patient comfort and decrease the frequency of post-operative nausea and vomiting. In this case report, the TPVB was presented which was performed for two patients with high risk of anesthesia who have been planned to undergo open cholecystectomy.

The favorable kinetic properties of sevoflurane could be advantageous in obese patients undergoing bariatric surgery, improving recovery from general anesthesia (GA). ⋯ Sevoflurane has a better recovery profile based on eye opening, obeying commands, time for extubation and orientation, than isoflurane in morbidly obese patients undergoing laparoscopic sleeve gastrectomy.

Pregabalin and clonidine have anti-nociceptive properties. This study assesses their efficacy in prolonging the analgesic effect of spinal anesthesia and post-operative analgesic requirement in patients undergoing vaginal hysterectomy. ⋯ Oral pregabalin (150 mg) prolongs the post-operative pain relief after spinal anesthesia but produces less sedation compared with oral clonidine (150 μg).

The case report here is a case of cesarean operation under subarachnoid block, which resulted after a failed lumber puncture, known to be "dry tap." The result is that it was uneventful surgery without any additive anesthetics being required after injecting 2.2 ml Bupivacaine 0.5% (H). Although cases have been reported with mixed experiences of dry tap and different causes are also explained, but still there is a need to find few other reasons for "dry tap." Hence, thought to present the case for putting forward a question that if there is any more cause for dry tap.

The aim of the present study is to substantiate and compare the quality and extent of nerve block by using intrathecal bupivacaine or extradural bupivacaine alone and in combined spinal-epidural (CSE) technique using smaller dose of intrathecal bupivacaine and extradural injection of a smaller dose of bupivacaine or normal saline. ⋯ Quality of nerve block in combined technique using bupivacaine both intrathecally and extradurally is better and associated with lower side-effect compared with intrathecal heavy bupivacaine or extradural isobaric bupivacaine alone.
