ABSTRACT
Background: The I-gel is a latex-free SAD that has a non-inflatable cuff and medical-grade thermoplastic elastomer. The design allows for a more close interaction when engaging with supraglottic tissue. The goal of the present prospective study was to compare the performance of the I-gel with that of the LMA-Supreme. Methods: The present prospective study was conducted on 100 adult patients with age between 18 to 60 years with American Society of Anesthesiologists (ASA) physical status I or II who were scheduled to undergo elective laparoscopic Gynecological procedure under general anesthesia were included in the study. Patient having gastric reflux, Obesity (BMI >30kg/m2), cervical spine disease or difficult airway were excluded from the study. The study was conducted after obtaining approval from the Institutional Review Board. A written informed consent for participation in the study was obtained from each patient. Results: The mean time for insertion in the Group SLMA was 29 sec which was significantly more as compared to 21 sec in Group I-gel (p<0.0001). 84% cases from the Group I-gel had ease of insertion which was significantly more as compared to 82% among the Group SLMA. There was no significant difference in the incidence of postoperative complications between the groups (p>0.05). Conclusion: In conclusion, both devices were similarly successful ventilatory devices for gynaecological laparoscopic procedures in terms of ease of insertion, first-time success rates, time to insertion, and oropharyngeal leak pressure
ABSTRACT
Objective@#To observe the application of ultrasound-guided femoral nerve block(FNB) and popliteal sciatic nerve block(PSNB) in patients undergoing foot and ankle surgery.@*Methods@#From August 2015 to August 2017, 60 patients scheduled for foot and ankle surgery undergoing laryngeal mask airway (LMA) general anesthesia in the People′s Hospital of Langfang were randomly divided into 3 groups by the random number table, with 20 cases in each group.Before transfer patients from bed to operating table, A group received dezocine 5 mg iv, B group received FNB combined with PSNB(distal to the sciatic nerve bifurcation), C group received FNB combined with PSNB(proximal to the sciatic nerve bifurcation). A total of 40 mL of 0.375% ropivacaine were injected guided by ultrasound in B group and C group.The time of sufficient sensory block and awake, the dosage of remifentanil and propofol were recorded.Pain was assessed using visual analogue scale (VAS) pre- and post block.The incidence of sleepiness, postoperative nausea and vomiting (PONV), agitation, pain and adverse reaction were also recorded.@*Results@#The time of sufficient sensory block and awake, the dosage of remifentanil and propofol in A, B and C group: A group(not measured), (21.6±1.6)min, (1183±17)μg, (665.0±6.7)mg; B group (25.5±2.5)min, (15.3±1.4)min, (635±16)μg, (455.0±6.5)mg; C group (19.6±2.3)min, (14.9±1.5)min, (598±14)μg, (438.0±9.9)mg.The time of awake, the dosage of remifentanil and propofol in B group and C group were significantly lower than those in A group (F=44.07, 52.41, 62.45, all P<0.05).

ABSTRACT
Objective To evaluate the different effects of laryngeal mask and mask ventilation during bronchoscopy in elder patients. Methods 120 old patients (ASA I-III) were divided into three group according to the table of random number as following:surface anesthesia with autonomous respiration (group I);endoscope mask ventilation (group II);laryngeal mask airway ventilation (group III). Oxygen inhalation through nasal tube in groupⅠ,group II and group III was ventilated with endoscope mask and LMA respectively ,thenwe observed whether there were adverse effects or not during the procedure. Results The adverse reactions of group I were more than other groups. Compared with the group I, variance of MAP,HR, RR, SpO2 in the groupⅡand groupⅢ had less changes, the cases with severe bucking decreased significantly, and satisfaction degree increased markedly, (P <0.01or P<0.05 ) . The incidence rate of resp iratory depression and airway obstruction in groupⅡwas higher than that in groupⅢ (P<0.05). Conclusion Endoscope mask ventilation and LMA can both be adopted in analgesia bronchoscopy for old patient. LMA under general anesthesia to transbronchial lung biopsy would control respiration according to the demand at any time.LMA has more advantage in the operation for the stable respiration and hemodynamics and less complications.
ABSTRACT
ObjectiveTo compare the clinical efficacy and safety of anesthesia induction between inhalation of sevoflurane and intravenous injection of propofol for laryngeal mask airway (LMA) insertion in elderly patients.Methods40,ASA physical grade Ⅰ ～ Ⅱ patients scheduled to receive elective total knee arthroplasty were allocated to 2 groups at random. Patients in group one( G1 ) received intravenous induction of propofol infusion by a targetcontrolled infusion system which was set at the effect-site concentration of 4.0μg/ml,while patients in group two(G2)received inhalational induction with sevoflurane using vital capacity manoeuver at the target of end-expiratory concentration of 3.0％. We observed the whole procedure of anesthesia induction and LMA insertion, while recording the changes in hemodynamic state and occurrence of adverse events. ResultsMore than 85％ patients achieved LMA insertion at first attempt using either induction manoeuver. Although consciousness loss time in G1 was 39. ls longer than G2, there was no difference in anesthesia induction time for LMA insertion between these two groups. Contrary to a significant decrease in MAP following induction for patients in G1, there appeared hemodynamically stable in patients of G2,while apnea also significantly seldom occurred in G2 as compared to G1 (20％ vs 85％ ,P ＜0. 05).ConclusionAs compared to intrvenous induction with propofol, inhalation induction with sevoflurane provided a valuable alternative for LMA insertion in adults.
