Objective To systematically assess the effectiveness and safety of streamlined liner of the pharynx airway (SLIPA) compared with endotracheal tube (TT) for airway management in patients undergoing laparoscopic cholecystectomy surgery. Methods Databases such as PubMed (1992 to February 2012), EMbase (1984 to February 2012), MEDLINE (Ovid, 1964 to February 2012), SCI (1992 to February 2012), CNKI (1992 to February 2012), CBM (2002 to 2012) as well as WanFang Data (1992 to February 2012) were searched for relevant literature. The references of the included articles were also manually traced. Two reviewers independently screened the trials according to inclusion and exclusion criteria, extracted the data, and assessed the quality of methodology. Meta-analyses were performed using RevMan 5.0 software. Results Ten randomized controlled trials (RCTs) involving 664 patients were included. Results of meta-analysis showed that: a) as for side effects, none of the patients experienced regurgitation or hypoventilation during operation; b) as for extubation response, SLIPA was proved fewer than TT during extubation with a significant difference (RR=0.14, 95%CI 0.05 to 0.36, Plt;0.000 1); c) SLIPA was superior to TT with regard to reducing postoperative sore throat (RR=0.15, 95%CI 0.06 to 0.38, Plt;0.000 1); d) SLIPA was similar to TT with regard to Ppeak after peritoneal insufflations (WMD=–0.07, 95%CI –0.73 to 0.59, P=0.83); e) as for PETCO2, the SLIPA group was lower than the TT group obviously after peritoneal insufflations (WMD=–1.09, 95%CI –1.70 to –0.49, P=0.000 4); f) as for hemodynamic change, the SLIPA group was more stable than the TT group during the operation with significant differences (Plt;0.05). Conclusion Current studies suggest that it is safe and effective to apply SLIPA for ventilation in laparoscopic cholecystectomy surgery. However, due to the limited quantity and quality of the included studies, more high-quality studies are need.
Objective To assess the effectiveness and safety of laryngeal mask airway (LMA) and endotracheal tube (ETT) for airway management in pediatric general anesthesia. Methods Randomized controlled trials were collected through electronic searches of the PubMed, The Cochrane Library, EMbase, CBM, WanFang Data, VIP, CNKI from the date of establishment to November 2010. All the related data that matched the standards were abstracted by two reviewers independently. The quality of the included trials was evaluated according to the Cochrane Handbook 5.0. RevMan 5.0 software was used for meta-analysis of the complications, success of insertion on the first attempt and hemodynamic changes. Results A total of 39 trials involving 2 612 patients were included. The results of meta-analyses showed that LMA was superior to ETT in terms of less cough (RR=0.21, 95%CI 0.15 to 0.28, Plt;0.000 01), laryngospasm or bronchospasm (RR=0.37, 95%CI 0.18 to 0.77, P=0.008) and agitation (RR=0.14, 95%CI 0.09 to 0.22, Plt;0.000 01) during emergency. The incidence of postoperative sore throat (RR=0.32, 95%CI 0.19 to 0.55, Plt;0.000 1), hoarse voice (RR=0.09, 95%CI 0.03 to 0.27, Plt;0.000 1), nausea and vomiting (RR=0.46, 95%CI 0.26 to 0.80, P=0.006) was significantly lower in the LMA group. The hemodynamic changes during insertion and extraction of LMA were more stable than ETT, such as the heart rate changes in insertion, extraction and post-extraction period (SMD= –1.18, 95%CI –1.59 to –0.77, Plt;0.000 01; SMD= –1.29 95%CI –1.72 to –0.86, Plt;0.000 01; and SMD= –1.51 95%CI –2.15 to –0.87, Plt;0.000 01, respectively) and the MAP changes in insertion, extraction and post-extraction period (SMD= –1.21, 95%CI –1.39 to –1.02, Plt;0.000 01; SMD= –1.31, 95%CI –1.77 to –0.85, Plt;0.000 01; and SMD= –0.85, 95%CI –1.24 to –0.46, Plt;0.000 1, respectively); but no significant differences in postoperative regurgitation and aspiration (RR=3.00, 95%CI 0.62 to 14.61, P=0.17) and successful insertion on the first attempt (RR=0.99, 95%CI 0.94 to 1.05, P=0.84) were found between the LMA and ETT groups. Conclusion Current evidence indicates that the laryngeal mask airway is superior to endotracheal tube in terms of fewer complications during emergency and after operation as well as stable hemodynamic changes. So, it is a selective, safe and effective airway management for children.
Objective To systematically assess the effectiveness and safety of ProSeal laryngeal mask (PLMA) compared to endotracheal tube (TT) for airway management in the patients undergoing laparoscopic biliary tract surgery.Methods Using the Cochrane systematic review methods, we searched the Cochrane Controlled Trial Registers (CCTR) of The Cochrane Library, MEDLINE, VIP, and CNKI databases through May 2008. We also handsearched relevant journals and conference proceedings. Two reviewers independently selected studies and assessed the quality of the trials. Disagreements were resolved by discussion, in consultation with a third reviewer. RevMan 4.2 software provided by the Cochrane Collaboration was used for meta-analysis which was performed for combining the results of homogeneitystudies. Results Seven studies involving 493 patients undergoing laparoscopic biliary tract surgery were included. Meta analysis results showed that: ① Side effects: none of the patients experienced regurgitation or hypoventilation. ② PLMA was superior to TT in terms of less postoperative sore throat (OR=0.27, 95%CI 0.13 to 0.53, P=0.0002) and response during extubation (OR=0.01, 95%CI 0.00 to 0.03, Plt;0.00001). ③ PLMA was similar to TT in terms of effective ventilation during peritoneal insufflation (Ppeak: WMD=0.01, 95%CI -0.66 to 0.68, P=0.98; PetCO2: WMD=0.01, 95%CI -0.58 to 0.59, P=0.99) and ease of insertion (OR=0.58, 95%CI 0.23 to 1.47, P=0.25). ④ Hemodymatics changed during the procedure: PLMA was more stable than TT. Conclusion It is safe to use PLMA for ventilation in laparoscopic biliary tract surgery. However, up to now, we still cannot draw a definite conclusion due to the low quality of the included studies, and more high quality trials of PLMA airway management for laporoscopic surgery are needed.

Methods From April 2009 to February 2010, 46 patients requiring general anesthesia using laryngeal mask airway (LMA) (American Society of Anesthesiologists (ASA)Ⅰ-Ⅱ) aged 18-60 were randomly divided into two groups: 23 in etomidate emulsion group (group E) underwent the intravenous injection with midazolm (0.3 mg/kg) and etomidate (0.05 mg/kg); 23 in etomidate emulsion + sufentanil group (group ES) underwent the intravenous injection with etomidate (0.15 mg/kg), midazolm (0.05 mg/kg), and sufentanil 0.5 mg/kg. The patients were evaluated by six indexes of LMA insertion (mouth opening, swallowing reflex, cough reflex,vomiting reflex, body motion, and laryngospasm classification). After the anesthesia induction, LMA was inserted. The blood pressure (BP), heart rate (HR), and mean arterial pressure (MAP) were recorded before anesthesia induction one minute after the injection and one minute after LMA insertion. Meanwhile, the apnea time was recorded. Results Compared with group E, group ES offered better anesthesia for LMA insertion, less swallowing reflex and body motion, and more stable haemodynamics. Conclusion Etomidate combined with sufentanil provides good condition for LMA insertion under the general anaesthesia with steady haemodynamics.

Methods From June 2009 to February 2010, 40 children scheduled to undergo general anesthesia for minor surgical procedures in lateral position were randomly divided into the laryngeal mask airway group (group L) and the tracheal tube group (group T) with 20 in each. Heart rate (HR), mean arterial pressure (MAP), pulse oxygen saturation (SpO2), top airway pressure (Pmax) of the patients were observed. In addition, side effects such as nausea, vomiting, and emergence agitation were also recorded. Results HR and MAP of patients in group T were significantly higher than those of patients in group L after intubation and after extubation (Plt;0.05). There was no difference in Pmax and SpO2 between the two groups (Pgt;0.05). The incidence of emergence agitation in group T was significantly higher than that in group L. Conclusions LMA intubation can provide the same safe and effective ventilation as tracheal intubation for children undergoing lateral general anesthetic operation. LMA is superior to tracheal intubation in insertion response, and the incidence of emergence agitation is lower.
