Addition of Dexmedetomidine to Ropivacaine in Subcostal Transversus Abdominis Plane Block Potentiates Postoperative Analgesia among Laparoscopic Cholecystectomy Patients: A Prospective Randomized Controlled Trial.

Context: 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.

Aims: We hypothesized that a subcostal TAP block with ropivacaine and dexmedetomidine will prolong the duration of postoperative analgesia following laparoscopic cholecystectomy.

A Comparative Study of Two Different Intravenous Bolus Doses of Phenylephrine Used Prophylactically for Preventing Hypotension after Subarachnoid Block in Cesarean Sections.

Background And Aims: Hypotension occurs in most of the cases following subarachnoid block in for cesarean sections. Studies comparing different bolus doses of phenylephrine for preventing hypotension induced by subarachnoid block in cesarean sections are sparse.

Settings And Design: This study was conducted to compare the efficacy of two different bolus doses of phenylephrine for preventing subarachnoid block-induced hypotension in cesarean sections.

Attenuation of Hemodynamic Response to Tracheal Extubation: A Comparative Study between Esmolol and Labetalol.

Background And Aims: Cardiovascular stress response to extubation can result in elevated heart rate (HR) and mean arterial blood pressures which can be detrimental in high-risk patients.

Settings And Design: The objective of this study is to compare the esmolol and labetalol efficacy in attenuating hemodynamic response to tracheal extubation.

Materials And Methods: Sixty patients scheduled for elective surgical procedures were selected randomly and divided into two groups of thirty each.
