Dexmedetomidine Versus Fentanyl on Time to Extubation in Patients with Morbid Obesity Undergoing Laparoscopic Sleeve Gastrectomy.

Background: Sleeve gastrectomy (SG) is an effective method for managing obesity. While opioids are used for their hemodynamic stability and their ability to reduce intraoperative stress, they also have reported side effects. Dexmedetomidine (DEX), an α2 adrenergic receptor agonist, is noted for its analgesic and anesthetic-sparing effects, leading to a higher quality of recovery.

Comparison Between Erector Spinae Plane Block versus Serratus Anterior Plane Block Regarding Analgesia and Stress Response After Modified Radical Mastectomy: Randomized Controlled Trial.

Background: Modified radical mastectomy (MRM) is the primary surgical treatment for breast cancer, yet it leads to significant postoperative pain.

Objectives: This randomized controlled trial evaluates the effects of an erector spinae plane block (ESPB) versus a serratus anterior plane block (SAPB) on post-MRM pain management and stress response reduction.

Methods: Sixty individuals scheduled for unilateral MRM under general anesthesia from October 2021 to October 2022 were divided into three groups.

Intrathecal Injection of Hyperbaric Bupivacaine Versus a Mixture of Hyperbaric and Isobaric Bupivacaine in Lower Abdominal Surgery: A Randomized Controlled Trial.

Background: Bupivacaine hydrochloride is widely used as the primary drug for spinal anesthesia.

Objectives: This research aimed to evaluate the intrathecal administration of both isobaric and hyperbaric bupivacaine (HB) in lower abdominal surgery.

Methods: A randomized, controlled, double-blind trial was conducted on 50 patients classified as American Society of Anesthesiologists (ASA) class I to II, scheduled for lower abdominal surgery under spinal anesthesia.
