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.

Catheter-related bladder discomfort (CRBD) is the most distressing symptom in patients due to intraoperative urinary catheterization. Amikacin significantly inhibits detrusor contraction evoked by prejunctional stimulation. ⋯ Amikacin can significantly reduce the incidence and severity of CRBD in the first few hours after surgery.

To study the efficacy and safety of intrathecal neostigmine at dose of 50 μg and 150 μg as an adjuvant to bupivacaine for postoperative analgesia under spinal anesthesia. ⋯ The administration of intrathecal neostigmine in dose of 50 μg as an adjuvant to bupivacaine produces hemodynamically stable analgesia with minimal side effects.

Postoperative nausea and vomiting (PONV) is one of the complex and significant problems in anesthesia practice, with growing trend toward ambulatory and day care surgeries. This review focuses on pathophysiology, pharmacological prophylaxis, and rescue therapy for PONV. We searched the Medline and PubMed database for articles published in English from 1991 to 2014 while writing this review using "postoperative nausea and vomiting, PONV, nausea-vomiting, PONV prophylaxis, and rescue" as keywords. ⋯ Newer drugs such as neurokinin-1 receptor antagonist (aprepitant) are used along with serotonin (5-hydroxytryptamine subtype 3) receptor antagonist, corticosteroids, anticholinergics, antihistaminics, and butyrophenones for PONV prophylaxis. Combination of drugs from different classes with different mechanism of action are administered for optimized efficacy in adults with moderate risk for PONV. Multimodal approach with combination of pharmacological and nonpharmacological prophylaxis along with interventions that reduce baseline risk is employed in patients with high PONV risk.

Sufentanil is widely used for patient-controlled intravenous analgesia (PCIA). Oxycodone has a powerful analgesic effect and mild side effects. We conducted this study to compare the efficacy of oxycodone and sufentanil for PCIA on postoperative pain after laparoscopic radical gastrectomy. ⋯ Oxycodone is a valuable alternative for PCIA in patients undergoing laparoscopic radical gastrectomy.
