RESUMEN
Objective • To observe the correlation between streamlined liner of pharynx airway (SLIPA) and gastric insufflation. Methods • Seventy patients who underwent elective general anesthesia in Jiading District Central Hospital Affiliated to Shanghai University of Medicine & Health Sciences from September 2017 to May 2018 were included. They were randomly divided into SLIPA group (S group, n=35) and endotracheal tube group (T group, n=35). The gastric antrum ultrasonography was performed at four time points before induction, immediately after intubation (insertion of laryngeal mask), before extubation (laryngeal mask), and immediately after extubation (laryngeal mask), to measure the cross sectional area (CSA) of gastric insufflation. Gastric intake was assessed by ultrasonic measurement of CSA and "comet tail sign" in ultrasound imaging. Pulse oxygen saturation (SpO2), end-tidal pressure of carbon dioxide (PETCO2), peak inspiratory pressure (PIP) and CSA were recorded and compared at the corresponding time points. Results • There was no significant difference in gastric insufflation rate between the two groups during anesthesia (P=0.894). There was no significant difference in SpO2 at each time point between the two groups (all P>0.05). At the end of surgery, PETCO2 in group S was significantly higher than that in group T (P=0.000). Conclusion • Compared with endotracheal tube, the SLIPA does not increase gastric insufflation during general anesthesia.
RESUMEN
Objective To analyze the application effect and safety of streamlined liner of the pharynx airway (SLIPA) anesthesia in painless fiberoptic bronchoscopy (FB).Methods Two hundred and eighty-two patients who undorwent FB examination in Kaifeng Second People's Hospital from January 2015 to January 2017 were selected and divided into observation group and control group,with 141 patients in each group.The patients in observation group were given SLIPA assisted anesthesia;the patients in control group were given endoscopic mask assisted anesthesia.The oxygen saturation (SpO2),systolic blood pressure (SBP),diastolic pressure (DBP) and heart rate (HR) of patients in the two groups were monitored.The changes of SBP,DBP and HR,the incidence of adverse reactions and the satisfaction of patient to the anesthesia were compared between the two groups.Results The fluctuation of HR,SBP and DBP of patients in the observation group was (3.52 ± 2.92) times · min-1,(7.04 ±5.30) mmHg(1 mmHg =0.133 kPa),(1.52 ± 1.63) mmHg respectively and in the control group was (5.52 ± 1.89) times · min-1,(30.12 ± 8.88) mmHg,(4.06 ± 5.78) mmHg respectively;the fluctuations of HR,SBP and DBP of patients in the observation group were significantly less than those in the control group(P ＜ 0.05).In the observation group,12 patients with cough,8 patients with abdominal distension,6 patients with pharyngeal pain,2 patients with SpO2 ≤90％,4 patients with SpO2 ＜ 85％;in the control group,57 patients with cough,32 patients with abdominal distension,47 patients with pharyngeal pain,28 patients with SpO2 ≤90％,19 patients with SpO2 ＜ 85％.The incidence of adverse reactions of patients in the observation group was significantly lower than that in the control group (x2 =27.10,61.82,41.59,72.46,87.75;P ＜0.05).The anesthesia satisfaction of patients in the observation group(97.87％) was significantly higher than that in the control group(82.98％) (x2 =29.97,P ＜ 0.05).Conclusion SLIPA assisted anesthesia has good clinical effect and safety in patients with painless FB.
RESUMEN
Objective To compare new type streamlined liner pharynx airway with standard type Ⅰ laryngeal mask airway in the clinical effectiveness in gynecologic laparoscopic surgery.Methods Seventy three cases undergone gynecologic laparoscopic surgery were divided into two groups randomly.The observation group(40 cases) and the control group(33 cases) were maintained by streamlined liner pharynx airway(SLIPA) and standard type Ⅰ laryngeal mask airway respectively.The success rate of placement,throat hemorrhage and pain before/after anesthesia and other indicators.were strictly observed and recorded during anesthesia.Results The success rate of placement was significantly higher in the observation group than in the control group(P＜0.05).The incidence of throat hemorrhage and throat pain after surgery were significantly lower in the observation group(P＜0.05).Conclusion The streamlined liner pharynx airway could be easyly and safely placed and causes less tissue injury and complications in gynecologic laparoscopic surgery.SLIPA was worthy of being recommended in clinical surgery.
