Randomized Controlled Trial
Effects of dexmedetomidine administered for postoperative analgesia on sleep quality in patients undergoing abdominal hysterectomy.
To evaluate the effects of postoperative dexmedetomidine infusion on sleep quality in patients undergoing abdominal hysterectomy. ⋯ Dexmedetomidine infusion not only offers effective analgesia but also improves postoperative sleep quality in patients undergoing hysterectomy.

Comparative Study Clinical Trial
Dexmedetomidine decreases the required amount of bupivacaine for ultrasound-guided transversus abdominis plane block in pediatrics patients: a randomized study.
The effect of dexmedetomidine on the potency of bupivacaine for transversus abdominis plane (TAP) block in pediatric patients has not been investigated. ⋯ The addition of 2μg/kg of dexmedetomidine reduced the minimum local anesthetic concentration of bupivacaine used for a TAP block and improved postoperative analgesia in children undergoing surgery for inguinal hernia repair or hydrocelectomy.

Comparative Study
Dexamethasone and perioperative blood glucose in patients undergoing total joint arthroplasty: A retrospective study.
Perioperative dexamethasone is commonly used to prevent nausea. It can also increase blood glucose levels, and recent concern about its blood glucose-elevating effect in humans has been raised. This study aimed to demonstrate relationships between dexamethasone administration and elevated perioperative blood glucose in patients undergoing total joint arthroplasty. ⋯ There was no evidence of an association between perioperative dexamethasone administration and the odds of having postoperative glucose levels >200mg/dl or higher maximum glucose levels. However, these findings may not be generalizable to patients having different baseline characteristics or procedures.

Comparative Study Clinical Trial
Cardiac output changes with phenylephrine and ephedrine infusions during spinal anesthesia for cesarean section: A randomized, double-blind trial.
Hypotension is a common side effect of spinal anesthesia. Phenylephrine and ephedrine are the two most frequently used vasopressors to treat spinal hypotension during cesarean delivery. In this randomized double-blind study, we aimed to evaluate cardiac output (CO) changes with phenylephrine or ephedrine infusions titrated to maintain baseline systolic blood pressure (bSBP) during spinal anesthesia. ⋯ The maximum increase in CO from the baseline was 12%, in the ephedrine group, and this occurred 20 minutes after spinal injection. Cardiac output fell by more than 17% in the phenylephrine group, maximal at 10 minutes following spinal injection. Despite good systolic blood pressure control and increased cardiac output with ephedrine, administration of ephedrine was associated with significantly more fetal acidosis [Median (Interquartile range, IQR) UApH - phenylephrine = 7.33 (7.31-7.34) and ephedrine = 7.22 (7.16-7.27), P < .05].

Randomized Controlled Trial
Oblique approach for ultrasound-guided radial artery catheterization vs transverse and longitudinal approaches, a randomized trial.
To investigate the value of using a new technique for ultrasound-guided radial artery catheterization; oblique approach; vs transverse and longitudinal views are the traditionally used approaches aiming to combine benefits and avoid drawbacks of aforementioned approaches. ⋯ These results support the conclusion that the oblique approach for US-guided radial artery catheterization may replace the 2 classic approaches owing to its superior success rate, higher first attempt success and shorter time consumed for catheterization with more operator satisfaction after the procedure.
