Dexamethasone as an adjunct to ropivacaine has shown promising results in prolonging the duration of analgesia in transverse abdominis plane (TAP) block. Only limited studies evaluated the effects of dexamethasone with ropivacaine in TAP block in specific population. ⋯ Addition of dexamethasone to ropivacaine significantly improved the quality of analgesia with reduced consumption of opioids as compared to plain ropivacaine in TAP block.

Dexmedetomidine, a selective alpha 2 (α2)-adrenergic receptor agonist, has been used to blunt the hemodynamic response associated with laryngoscopy and tracheal intubation, which is a common concern for the anesthesiologist, especially in high-risk patients and geriatric age group. ⋯ This study concluded that more acceptable hemodynamic changes were seen with 0.50 μg/kg dexmedetomidine when compared with 1.0 μg/kg dexmedetomidine during intubation. A lower dose besides being cost-effective is also free of side effects associated with the higher dose of 1 μg/kg dexmedetomidine.

Transversus abdominis plane (TAP) block in cesarean section is carried out by local anesthetics such as bupivacaine or ropivacaine with a limited duration of analgesia. The addition of adjuvants such as clonidine and dexmedetomidine has increased the duration of postoperative analgesia. ⋯ The addition of clonidine 1 μg/kg to 20-ml levobupivacaine 0.25% in TAP block bilaterally for cesarean section significantly increases the duration of postoperative analgesia, decreases postoperative rescue analgesic requirement, and increases maternal comfort compared to 20 ml of levobupivacaine 0.25% alone.

Exposure to medications (prescribed or over-the-counter) or exposure to chemicals (unintentional or occupational) during pregnancy have always been of great scientific concerns. ⋯ Practice of inhalational induction of anesthesia was reportedly more common among Indian male anesthesiologists during periconceptional period of their second-born female children.

Lumbar Erector spinae Plane block (L-ESPB) is a modification of a recently described block. Both L-ESPB and Transmuscular Quadratus Lumborum block (QLB-T) have been reported to provide effective postoperative analgesia in hip and proximal femur surgery. Herein, we compare the effectiveness of L-ESPB and QLB-T in providing postoperative analgesia in patients undergoing hip and femur operations. ⋯ While L-ESPB and QLB-T have similar effect, they improve analgesia quality in patients undergoing hip and proximal femoral surgery when compared to standard intravenous analgesia regimen.
