Objective To explore the feasibility and safety of fentanyl, sufentanil or remifentanil combined with target-controlled infusion (TCI) of propofol for sedation in the elderly undergoing colonoscopy. Methods In this prospective randomized study, 60 patients undergoing colonoscopy and propofol TCI were randomly assigned to group F (fentanyl), group S (sufentanil) and group R (remifentanil)(each n=20). Patients in group F received a single bolus of fentanyl, while those in group S and group R received TCI sufentanil and remifentanil separately. The blood pressure, heart rate, blood oxygen content and Bispectral index (BIS) were monitored, and all the complications were recorded. Results All patients were adequately sedated. There were no significant differences in general conditions, hemodynamics changes, sedation depth and adverse event among the three groups (all P>0.05). Time for recovery was longer in group F [(21.3±4.6) min] than in group S [(19.9±3.3) min] and group R [(15.9±1.8) min, P<0.05]. Conclusions For the elderly undergoing colonoscopy, sedation with fentanyl, sufentanil or remifentanil combined with propofol TCI is feasible and safe. It is more excellent for the remifentanil group at shorter discharge time.

Objective To investigate the effect of different time administration of parecoxib sodium on the postoperative analgesic efficacy in patients undergoing thoracic surgery. Methods This was a prospective,randomized, double-blind, placebo-controlled study. Sixty ASA Ⅰ orⅡ patients aged 17-83 yr undergoing pulmonary lobectomy were randomly allocated to one of 3 groups (n=20 each):A, B and C groups. Group A received normal saline 2 ml at 30 min before skin incision and the end of operation. Group B received iv parecoxib sodium 40 mg at 30 min before skin incision and normal saline 2 ml at 30 min before the end of operation. Group C received normal saline 2 ml at 30 min before skin incision and iv parecoxib sodium 40 mg at 30 min before the end of operation. All the patients received patient-controlled intravenous analgesia with morphine and VAS score was maintained≤3. The patients were followed up after operation.The morphine consumption, patients' global evaluation of the postoperative analgesia (0-100, 0=worst pain, 100=no pain), nausea and vomiting, body temperature , volume o chest drainage, hepatic, renal and blood coagulation function were recorded. Results Compared with group A, the morphine consumption was significantly reduced, the patient' s satisfaction score increased and body temperature decreased in B and C groups(P<0.05 or 0.01). There was no significant difference in the morphine consumption, patient's satisfaction score and body temperature between B and C groups(P>0.05). No significant difference was found in the parameters of hepatic, renal and blood coagulation function, volume of chest drainage and incidence of nausea and vomiting among the three groups(P>0.05).Conclusion When postoperative analgesia is assisted with iv parecoxib sodium 40 mg given at 30 min before skin incision or at 30 min beforethe end of operation,the efficacy is similar,and both can improve the postoperative analgesic efficacy of morphine and reduce fever after operation in patients undergoing thoracic 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.
