Randomized Controlled Trial Multicenter StudyBispectral index monitoring prevent awareness during total intravenous anesthesia: a prospective, randomized, double-blinded, multi-center controlled trial.
Awareness is a serious complication of general anesthesia. In China, the incidence of intraoperative awareness was 1% in patients undergoing total intravenous anesthesia (TIVA). In this study, we compared the incidence of awareness between Bispectral index (BIS)-guided and routine TIVA protocol and evaluated the effect of BIS on preventing awareness. ⋯ BIS-guided TIVA (BIS was recommended to maintain between 40 - 60) decreased the risk of awareness compared with routine TIVA. The main reason for awareness was light anesthesia.

Randomized Controlled TrialEffects of preoperative ketamine on the endocrine-metabolic and inflammatory response to laparoscopic surgery.
Ketamine is hypothesized to reduce perioperative endocrine-metabolic and inflammatory responses in cardiac surgery patients. This randomized, placebo-controlled, double-blind study was performed to determine whether perioperative endocrine-metabolic and inflammatory responses are attenuated by preoperative administration of ketamine to healthy females receiving elective laparoscopic surgery. ⋯ Endocrine-metabolic and inflammatory responses to laparoscopic surgery are attenuated in part by pre-incisional administration of ketamine.

Randomized Controlled TrialSufentanil reduces emergence agitation in children receiving sevoflurane anesthesia for adenotonsillectomy compared with fentanyl.
Emergence agitation is a common problem in pediatric anesthesia, especially after sevoflurane induction and maintenance anesthesia. The purpose of this study was to investigate the effect of sufentanil to reduce emergence agitation after sevoflurane anesthesia in children undergoing adenotonsillectomy compared with fentanyl. ⋯ Administration of sufentanil at 0.2 µg/kg after induction of anesthesia reduced emergence agitation in children receiving sevoflurane anesthesia for adenotonsillectomy compared with fentanyl. This was without delaying the recovery time or causing significant hypotension.

Second-look arthroscopic evaluation of the articular cartilage after primary single-bundle and double-bundle anterior cruciate ligament reconstructions.
Several reports have shown the progression of articular cartilage degeneration after anterior cruciate ligament (ACL) reconstruction. No report has been published about the cartilage comparing changes after single-bundle (SB) and double-bundle (DB) ACL reconstructions. The purpose of this study was to evaluate the articular cartilage changes after SB and DB ACL reconstructions by second-look arthroscopy. ⋯ Patellofemoral cartilage degeneration continued to aggravate after ACL reconstruction. DB ACL reconstruction could significantly decrease the trochlea cartilage degeneration compared with SB ACL reconstruction.

Effect of endogenous hydrogen sulfide on oxidative stress in oleic acid-induced acute lung injury in rats.
Acute lung injury (ALI) is a common critical disease in emergency care. Oxidative stress plays an important role in the pathogenesis of ALI. Endogenous hydrogen sulfide (H(2)S) can inhibit oxidative stress in rat gastric mucosal epithelium. In this study, we examined the possible role of H(2)S in regulation of the oxidative stress in oleic acid-induced acute lung injury in rats. ⋯ Endogenous H(2)S could inhibit the oxidative stress in lung tissue in oleic acid-induced acute lung injury in rats.
