Anesthesia, essays and researches
-
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.

Laparoscopic cholecystectomy is associated with moderate intensity postoperative pain especially in the early postoperative period. Transversus abdominis plane (TAP) block has been shown to reduce pain scores and analgesic requirements after abdominal surgery. ⋯ Addition of dexmedetomidine to ropivacaine in TAP block prolongs postoperative analgesia and reduces opioid consumption without any major adverse effects.
-
Traditional truncal blocks are devoid of visceral analgesia. Quadratus lumborum (QL) block has shown greater efficacy in providing the same. ⋯ Patients who received QL block had a significant improvement in postoperative pain relief with reduced consumption of opioids.

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.
