Effects of perioperative magnesium sulfate infusion on intraoperative blood loss and postoperative analgesia in patients undergoing posterior lumbar spinal fusion surgery: A randomized controlled trial.

Objective: Many studies have suggested the anti-nociceptive role for magnesium either as an adjunct for postoperative pain. Although several studies have been carried out to evaluate the anti-nociceptive effect of magnesium, there is still considerable uncertainty.

Patients And Methods: Eighty patients who underwent posterior spinal fusion were randomly divided into two groups (magnesium and saline).

Pulmonary Edema Following Intrathecal Fluorescein Injection; a Case Report.

Intrathecal Fluorescein has been used widely for detection of cerebrospinal fluid (CSF) leakage. After administration of fluorescein many serious complications may happen. Pulmonary edema is one of the most serious complications that require emergency responses.

Comparison of the Effect of Bupivacaine in Combination with Dexmedetomidine with Bupivacaine Plus Placebo on Neonatal Apgar Score, Bispectral Index, and Sedation Level of Parturient Women.

Objectives: In this study, we aimed to compare the effects of bupivacaine alone and in combination with dexmedetomidine on postoperative analgesia, neonatal Apgar score, and bispectral index (BIS), which has been shown to correlate with increased sedation and loss of consciousness in women undergoing cesarean section under spinal anesthesia.

Methods: A total of 152 term parturient women scheduled to have elective cesarean section with American Society of Anesthesiologist (ASA) physical status I or II were allocated randomly into two groups to receive either bupivacaine plus placebo (BV group) or bupivacaine plus dexmedetomidine (BVD group). BIS, sedation scale scores, Apgar scores, and hemodynamic characteristics were recorded and statistically compared between the groups.
