Abstract：

Objective To assess the efficacy of laryngeal mask airway (LMA) i-gel in patients required insertion of nasogastric tube before laparoscopic surgery. Methods Fifty-five ASA Ⅰ - Ⅲ patients ( Mallampati Ⅰ -Ⅲ ), aged 26-64 yr, weighing 54-73 kg, scheduled for elective laparoscopic surgery were randomly divided into 2 groups: group Ⅰ ( n= 28) and group Ⅱ ( n = 27). The size of i-gel LMA was chosen based on the patient' s weight, and i-gel LMA was inserted after induction of anesthesia with TCI of propofol and remifentanil, and iv injection of rocuronium. In group Ⅰ , the nasogastric tube was inserted through the drain tube of i-gel LMA. In group Ⅱ , the nasogastric tube was inserted through the nostril before operation. The hemodynamic parameters, SpO2 ,PETCO2 and peak airway pressure were monitored during operation. The fiberoptic laryngoscopy scores were assessed and nasogastrice tube displacement was recorled after successful LMA placement. The LMA placement time, success rate of LMA placement at the first attempt, airway sealing pressure, the occurrence of air leakage of LMA, and nasogastric tube drainage were recorded. The problems after removal of the LMA were observed and the adverse reactions within 24 h after operation were recorded. Results The hemodynamics was stable and the SpO2,peak airway pressure were within the normal range during operation in both groups. There was no significant difference in the LMA placement time, success rate of LMA placement at the first attempt, nasogastric tube drainage rate, airway sealing pressure, incidence of air leakage, fiberoptic laryngoscopy scores, problems after removal of the LMA and adverse reactions between the two groups ( P ＞ 0. 05). Conclusion i-gel LMA can provide adequate ventilation and does not interfere with the nasogastric tube drainage during laparoscopic surgery and can be used effectively for the patients required insertion of nasogastric tube before operation.

Abstract：

Objective To assess the efficacy of laryngeal mask airway (LMA) i-gel used in patients undergoing laparoscopic gynecological surgery. Methods Sixty ASA Ⅰ or Ⅱ patients, aged 21-64 yr, weighing 4590 kg, undergoing elective laparoscopic gynecological surgery, were randomized into 2 groups ( n = 30 each):LMA i-gel group (group Ⅰ) and LMA Supreme group (group S) . Mallampatti test was performed before operation in both groups. Anesthesia was induced with target-controlled infusion of propofol (target plasma concentration 2.5-4.0 μg/ml) and remifentanil (target plasma concentration 3-6 ng/ml) . After the patients lost consciousness, rocuronium 0.6 mg/kg was given to facilitate the LMA insertion. LMA i-gel and LMA Supreme were inserted in I and S groups respectively. A gastric tube was inserted through the drain tube of the LMA. In group S the air was injected into the cuff to make intracuff pressure reach 60 cm H2O after successful LMA insertion. The LMA placement time, the number of attempts of LMA insertion, the number of attempts of gastric tube placement, the airway sealing pressure, the parameters of hemodynamics and ventilation, and complications (sore throat, odynopliagia,hoarseness) were recorded. The fiberoptic laryngoscopy scores were assessed after successful LMA placement. The anesthesia time and recovery time were also recorded. Results There was no significant difference in the anesthesia time, recovery time, LMA placement time, fiberoptic bronchoscopy scores and the parameters of hemodynamics and ventilation between the two group. The success rates of LMA and gastric tube placement were 100% in both groups. The airway sealing pressure was significantly higher, while the incidence of sore throat and odynopliagia was significantly lower in group I than in group S. Conclusion LMA i-gel provides adequate ventilation during operation with fewer complications and can be used effectively for gynecological laparoscopic surgery.

Laryngeal mask airway ProSeal provides higher oropharyngeal leak pressure than i-gel in adult patients under general anesthesia: a meta-analysis

Study Objectivei-gel is a single-use supraglottic airway device that has a gastric drain tube similar to laryngeal mask airway (LMA) ProSeal. Randomized trials, when compared i-gel with LMA ProSeal, reported a differing results. Primary objective of this study is to compare LMA ProSeal and i-gel in terms of oropharyngeal leak pressure.DesignMeta-analysis of randomized controlled trials where i-gel has been compared to LMA ProSeal in adult airway management during general anesthesia.SettingTeaching institutions.MeasurementsPubMed, PubMed Central, and Cochrane databases were searched with search words “i-gel,” “i-gel laryngeal mask airway,” “i-gel ProSeal,” and “i-gel LMA ProSeal” to find out the randomized controlled trials that compared i-gel with LMA ProSeal in terms of safety and efficacy. A total of 10 prospective randomized trials have been included in this meta-analysis.Main ResultsLMA ProSeal provides higher oropharyngeal leak pressure than i-gel (mean difference, 3.37 cm H₂O; 95% confidence interval, 1.80-4.95 cm H₂O; P< .0001). Time to insert the device, first insertion success rate, and ease of gastric tube insertion are similar with both the devices, but i-gel may be easier to insert. Although the reported complications are not frequent and not very serious, a significantly higher blood staining on the mask has been noted with LMA ProSeal (odds ratio, 0.27; 95% confidence interval, 0.13-0.56; P= .0004).ConclusionLMA ProSeal may still remain the supraglottic device of choice over i-gel in adult patients during general anesthesia as it provided better seal against leak pressure with comparable device insertion characteristics.     

经典与改良喉罩通气道（OPLACTM）在成年患者中的对比研究

背景我们开发了一种改良的一次性喉罩通气道（Oro-Pharyngo-LaryngealAirwayCap，OPLACTM）。本研究中我们对比了经典LMA喉罩（LMAClassicTM）与OPLAC的性能。方法这是一项在60例麻醉肌松的成年患者中进行的随机、单盲、交叉研究。麻醉诱导后，以不同顺序给每一例患者使用两种喉罩：30例患者中首先试插LMA，而在另30例患者中首先试插OPLAC。评估成功率、插入时间、光纤图像、气道峰压、密封压力、胃胀气的发生率、相应设备上的血迹以及术后咽喉疼痛的发生率等。结果两种喉罩初次试插的成功率都很高。OPLAC所需的插入时间明显短于LMA，光纤图像优于LMA。OPLAC密封压力明显更高，而胃部胀气的发生率更低。术后咽喉疼痛的整体发生率是13．33％。结论两种喉罩的通气阻力相当，且插入容易。OPLAC的插入时间更短、插入时间变异范围小、与咽喉贴合更好、更少；1起胃部胀气并且密封压更高。
