Randomized Controlled TrialIncidence of shivering after cesarean section under spinal anesthesia with or without intrathecal sufentanil: a randomized study.
Shivering is a cause of discomfort and dissatisfaction in patients undergoing cesarean section. The objective of this study paper was to assess the impact of intrathecal administration of sufentanil on the incidence of shivering after cesarean section. ⋯ It has been suggested that the addition of sufentanil to hyperbaric bupivacaine and morphine during spinal anesthesia for cesarean section provides a decrease in the incidence of shivering in the immediate postoperative period.

Randomized Controlled Trial Comparative StudyReducing the concentration to 0.4% enantiomeric excess hyperbaric levobupivacaine (s75: r25) provides unilateral spinal anesthesia. Study with different volumes.
Unilateral spinal anesthesia may be obtained with hypobaric or hyperbaric solution. The objective of this study was to compare different doses of enantiomeric excess hyperbaric levobupivacaine to achieve unilateral spinal anesthesia. ⋯ Spinal anesthesia with different volumes of enantiomeric excess hyperbaric bupivacaine (S75: R25) provided a 78% incidence of unilateral spinal block, with the smallest dose used (4 mg) the most efficient.

Randomized Controlled TrialAnalgesic efficacy of the intra-articular administration of S(+)- ketamine in patients undergoing total knee arthroplasty.
Total knee arthroplasty (TKA) is associated with significant postoperative pain. Many intra-articular (IA) agents have been used for postoperative analgesia with inconsistent outcomes. Ketamine's enantiomer S(+), S(+)- ketamine, was recently introduced commercially, with higher analgesic potency and less side effects than the racemic form. An experimental prospective randomized double-blind study was conducted to evaluate the analgesic efficacy of intra-articular S(+)- ketamine in patients undergoing primary TKA. ⋯ In this study, with this sample, the analgesic effect of IA S(+)- ketamine was not superior to saline solution in the postoperative period of TKA.

Randomized Controlled TrialEffects of preoperative sublingual misoprostol on uterine tone during isoflurane anesthesia for cesarean section.
Misoprostol would reduce the uterine bleeding after cesarean delivery without harmful effects on either mother or baby. We aimed to evaluate the effects of preoperative misoprostol on maternal blood loss, uterine tone, and the need for additional oxytocin after cesarean delivery under isoflurane anesthesia. ⋯ Preoperative administration of sublingual misoprostol 400μg is safe and effective in attenuating the maternal bleeding and uterine atony from isoflurane anesthesia for cesarean delivery.
