喉罩与气管插管对腹腔镜胆囊切除术患者术后躁动影响观察

Objective To observe the validity of Supreme laryngeal mask airway (SLMA) to prevent/reduce postoperative agitation after general anesthesia. Methods 180 cases of elective laparoscopic cholecystectomy were randomly assigned to SLMA group (L group, n=90) or endotracheal intubation group (T group, n=90). The incidence and severity of postoperative agitation were recorded both in the operation room and post-anesthesia care unit (PACU)(graded as 0 to 3). Results The incidence of postoperative agitation in L group was 7.78%, and 18.89% in T group (P＜0.01); the severity of postoperative agitation was obviously palliated in L group than in T group (P＜0.01). Conclusion Under general anesthesia, SLMA can effectively prevent/reduce the incidence of postoperative agitation in laparoscopic cholecystectomy patients.     

Total intravenous anesthesia with propofol： Case report

t is difficult for anesthesia care providers to reliably detect residual neuromuscular block in the operation room using standard clinical criteria. Respiratory function can be subtle affected during minimal neuromuscular blockade, which is the only complain of some patients undergoing general anesthesia. Studies have suggested that tota ntravenous anesthesia （TIVA） with propofol reduces the incidence of postoperation nausea and vomiting （PONV） and results in shorter emergence time. We report one anesthesia case with total intravenous anesthesia of propofol and remifentanyl without neuromuscular block, and get very satisfied outcome.     

Supreme喉罩用于腹腔镜手术患者气道管理的效果

Objective To assess the efficacy of laryngeal mask airway Supreme (LMA Supreme) used in patients undergoing laparoscopic surgery. Methods One hundred and twenty ASA I or Ⅱ patients of both sexes aged 35-60 yr weighing 48-85 kg undergoing elective laparoscopic surgery were randomized to 2 groups ( n = 60 each): LMA Supreme group (group S) and tracheal intubation group (group T). Mallampati test was performed before operation in both groups. The patients were classified as I - Ⅲ . In group S the LMA Supreme was inserted after induction of anesthesia with sufentanil 0.2 fig/kg, propofol 2-3 mg/kg and vecuronium 0.1 mg/kg. A gastric tube was inserted through the drain tube of the LMA Supreme. In group T the patients were intubated under direct laryngoscopy. The success rate, LMA placement/intubation time, success rate of gastric tube placement, airway seal pressure, SpO2, PETCO2 , peak airway pressure and complications (hypoxemia, nausea and vomiting, choking hoarseness, sore throat and regurgitation of gastric contents) were recorded. The duration of surgery, anesthesia time, extubation time and emergence time were also recorded. Results There was no significant difference in the success rate between the two groups. The placement and removal time and recovery time were significantly shorter in group S than in group T. The airway seal pressure was (25 ±4) cm H2O in group S. SpO2, PETCO2 and peak pressure were within normal range in both groups. The incidence of postoperative hypoxemia, choking and sore throat were significantly lower in group S than in group T. Conclusion LMA Supreme can provide adequate ventilation during operation with less complications and can be used effectively for laparoscopic surgery.

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.

510例腹腔镜联合纤维胆道镜胆总管切开取石术的临床应用

目的探讨腹腔镜联合纤维胆道镜治疗胆总管结石的可行性及临床应用价值。方法1998年～2007年对510例患者行腹腔镜胆总管切开取石(laparoscopic common duct exploration,LCDE),与同期300例开腹(opensurgery,OS)手术者比较。术前确诊者,术中直接行胆总管切开胆道镜取石;术前有黄疸史、胰腺炎史和(或)直接胆红素增高、胆系酶(AKP、GGT)增高者,或胆总管在0.8cm以上者行术中造影,明确有胆总管结石的切开胆总管胆道镜取石。405例置T管引流(留置T管组),105例行胆总管Ⅰ期缝合(I期缝合组)。结果手术均获成功,与OS组比较,手术时间、术中出血量、术后并发症发生率(胆瘘、出血)差异无统计学意义;住院日、术后镇痛药使用次数、腹腔或切口感染率、残石率明显减少。无中转开腹。30例T管引流口靠近肋弓而引起术后疼痛,2例术后2dT管才引流出胆汁。留置T管组有24例胆总管残余结石,3月后经胆道镜取石成功。留置T管组手术时间平均(110±15)min,平均术后住院8d;Ⅰ期缝合组手术时间(95±8)min,平均术后住院5d。结论LCDE是治疗胆总管结石安全、有效的方法,同样可起到创伤小、痛苦轻、恢复快、住院时间缩短等微创效果,如能在取净结石的情况下行胆总管Ⅰ期缝合,微创效果尤为明显。     

Clinical outcomes in patients with renal artery stenosis treated with stent placement with embolic protection compared with those treated with stent alone

Purpose: To compare the clinical outcomes in patients with chronic renal insufficiency (CRI) and renal artery stenosis (RAS) following renal artery (RA) stent placement with and without embolic protection device (EPD) usage. Materials and Methods: Eighteen patients who had RA stent placement with EPD were matched to control patients (RA stent only). Blood pressure, number of hypertensive medications, and estimated glomerular filtration rate (eGFR) at 3 months before the procedure and after 12 months were determined. An increase of ≥ 20% in eGFR at 12 months from baseline was defined as "improvement," decrease of ≥20% as "deterioration," and an eGFR change between those values as "stabilization" at 12 months. Results: At 12 months, stage 4 patients treated with EPD had significantly higher eGFR than controls (P = .01). There was no statistical difference in blood pressure outcomes between the 2 groups. Conclusions: Patients with stage 4 CRI did significantly better with EPD than those treated without it.
