Randomized Controlled TrialEffects of pretreatment with a small dose of dexmedetomidine on sufentanil-induced cough during anesthetic induction.
We aimed to investigate the effects of pretreatment with a small dose of dexmedetomidine on the cough caused by sufentanil during anesthetic induction. ⋯ Dexmedetomidine at 0.10, 0.25, and 0.50 μg/kg significantly reduced the incidence of sufentanil-induced cough during anesthetic induction, with the effect being most marked for 0.10 μg/kg dexmedetomidine.

Randomized Controlled Trial Comparative StudyComparison of the effects of intranasal midazolam versus different doses of intranasal ketamine on reducing preoperative pediatric anxiety: a prospective randomized clinical trial.
To compare the effects of intranasal midazolam versus different doses of intranasal ketamine on reducing preoperative pediatric anxiety. ⋯ Intranasal midazolam was more effective than low- or high-dose intranasal ketamine in reducing preoperative pediatric anxiety. The lower dose of ketamine reduced preoperative anxiety more than a higher dose of ketamine, which may be clinically insignificant.

Randomized Controlled TrialPenehyclidine enhances the efficacy of tropisetron in prevention of PONV following gynecological laparoscopic surgery.
Postoperative nausea and vomiting (PONV) are common complications after gynecological laparoscopic surgery. Because monotherapy with antiemetics is insufficient, combinations of various antiemetics are often recommended by experts. In this study, our purpose was to find out whether penehyclidine could enhance the efficacy of tropisetron in preventing PONV. ⋯ Penehyclidine showed less efficacy in preventing PONV than tropisetron; however, compared with tropisetron or penehyclidine monotherapy, prophylactic medication with tropisetron plus penehyclidine significantly reduced the incidence of vomiting and decreased the intensity of nausea in women undergoing gynecological laparoscopic surgery.

Randomized Controlled TrialEffects of oral rehydration therapy on gastric volume and pH in patients with preanesthetic H2 antagonist.
Recent preanesthetic fasting practice allows patients to take clear fluids up to 2 h before surgery without taking any antacid for the prophylaxis of aspiration pneumonia; this practice is defined as oral rehydration therapy (ORT). It has been reported that with ORT the gastric volume may be significantly lower than that with a standard fasting regimen, although in a standard fasting regimen without preanesthetic antacid, gastric pH and volume values could be critical for causing aspiration pneumonia. In this study we compared gastric fluid status in patients with ORT and those with a standard fasting regimen; patients in both groups received a preanesthetic H(2) antagonist. ⋯ After the induction of anesthesia, the gastric contents were collected via a gastric tube to measure gastric volume and pH. Neither gastric volume nor pH differed between the groups (ORT 9.6 ± 8.2 ml and 5.6 ± 1.7, respectively, vs. standard fasting 8.5 ± 6.8 ml and 5.5 ± 1.7, respectively). These data suggest that ORT may not reduce gastric volume in patients receiving a preanesthetic H(2) antagonist.

Randomized Controlled TrialAdding pregabalin to a multimodal analgesic regimen does not reduce pain scores following cosmetic surgery: a randomized trial.
Multimodal analgesia increases the chance of successful discharge and pain control after surgery, and pregabalin is being promoted as an effective analgesic, based on placebo-controlled studies. We investigated whether adding pregabalin improved pain control and reduced opioid requests when it was added to a multimodal analgesic regimen for cosmetic surgery. ⋯ Perioperative pregabalin 75 mg twice a day does not increase benefit when it is added to an already multimodal analgesic regimen for patients undergoing cosmetic surgery. Several factors could explain our findings, including the possibility of publication bias in the current literature.
