Ultrasound-guided transversus abdominis plane (TAP) block is done as a part of multimodal analgesia for pain relief after abdominal surgeries. This prospective randomized, double-blind, placebo-controlled trial was conducted to evaluate the postoperative analgesic efficacy of bilateral TAP block in patients undergoing midline colorectal surgeries using ropivacaine. ⋯ TAP block produces effective and prolonged postoperative analgesia in patients undergoing midline colorectal surgery. It is a technically simple block to perform with a high margin of safety. It produces a considerable reduction in mean intravenous postoperative tramadol requirements, reduction in postoperative pain scores, and increased time to first request for further analgesia, both at rest and on movement.

Transversus abdominis plane (TAP) block has been used to provide intra- and post-operative analgesia with single incision laparoscopic (SIL) bariatric and gynecological surgery with mixed results. Its efficacy in providing analgesia for SIL cholecystectomy (SILC) via the same approach remains unexplored. ⋯ USG bilateral TAP blocks were not effective in decreasing 24 h morphine requirement as compared to local anesthetic infiltration in patients undergoing SILC although it provided some analgesic benefit intraoperatively and in the initial 4 h postoperatively. Hence, the benefits of TAP blocks are not worth the effort and time spent for administering them for this surgery.

This study aims to compare the minimum effective concentration of local anesthetic (LA) bupivacaine and ropivacaine with highly lipid soluble opioids fentanyl for providing optimal labor epidural analgesia. ⋯ In our study, both the drugs produced equivalent analgesia for labor at low concentration when used with highly lipid soluble opioid such as fentanyl.

For an outpatient surgery, an ideal anesthetic drug should have a faster onset and shorter duration of action and minimal side effects. Although Bupivacaine is a drug of choice in spinal anesthesia but is not suitable for ambulatory surgeries. We aimed to compare 1% 2-chloroprocaine (2-CP) which is considered to be a short-acting agent with 0.5% hyperbaric bupivacaine as a spinal anesthetic agent in ambulatory surgeries. ⋯ We concluded that 2-CP can be used for spinal anesthesia in shorter duration surgeries with early recovery from anesthesia and hence early discharge from the hospital.

Lumbar plexus block, combined with a sciatic nerve block, is an effective locoregional anesthetic technique for analgesia and anesthesia of the lower extremity. The aim of this study was to compare the clinical results outcome of the adductor canal block versus the psoas compartment block combined with sciatic nerve block using real time ultrasound guidance in patients undergoing elective laparoscopic knee surgeries. ⋯ The present study demonstrates that blockade of lumber plexus by psoas compartment block is more effective in complete sensory block without general anesthesia supplementation in addition to decrease post-operative analgesic requirement than adductor canal block.
