RESUMEN
Objective:To evaluate the effect of gender on neuromuscular blockade of rocuronium in epileptics.Methods:Forty American Society of Anesthesiologists physical status Ⅱ or Ⅲ patients, aged 18-59 yr, with body mass index of 18.5-24.0 kg/m 2, scheduled for elective surgery for treatment of epilepsy under general anesthesia, were divided into 2 groups ( n=20 each) according to gender: male group (group M) and female group (group F). Neuromuscular conduction function was monitored with a muscle relaxation monitor.Ulnar nerve was stimulated in TOF mode (frequency 2 Hz, wave width 0.2 ms, stimulation current 70 mA and interval 12 s). Rocuronium 0.8 mg/kg was injected intravenously during anesthesia induction, and endotracheal intubation was performed when T l reached maximum inhibition.The conditions of endotracheal intubation were evaluated by the modified method.When T 1 recovered to 25% during operation, rocuronium 0.15 mg/kg was intravenously injected.Sugammadex sodium 2 mg/kg was injected intravenously when T 1 recovered to 50% after surgery.The onset time (T onset), peak time (T peak), 10% recovery time (T 10%), 10%-25% recovery time (T 10%-25%), 25%-50% recovery time (T 25%-50%), 50%-75% recovery time (T 50%-75%) and 75%-90% recovery time (T 75%-90%) of rocuronium were recorded.Peripheral venous blood samples (3 ml) were collected when T 1 recovered to 25% and 75%, and the concentration of rocuronium was detected by liquid chromatography-tandem mass spectrum.The consumption of rocuronium per unit of weight per minute was calculated. Results:There was no significant difference between the two groups in terms of T onset, T peak, T 10%, T 10%-25%, T 25%-50%, T 50%-75%, T 75%-90%, endotracheal intubation conditions, blood concentration of rocuronium at varied time points, or consumption of rocuronium per unit of weight per minute ( P>0.05). Conclusion:Gender exerts no effect on the neuromuscular blockade of rocuronium in epileptics.
RESUMEN
Objective To observe the efficacy of oxycodone or fentanyl combined with flurbi-profen esters (FA)for postoperative analgesic after thoracic surgery.Methods Eighty patients,53 males and 24 females,aged 40-65 years,ASA physical status Ⅰ-Ⅲ,undergoing elective thoracotomy surgery,randomly divided into two groups (n =40 each).Oxycodone 0.1 mg/kg (group O)or fenta-nyl 1 μg/kg (group F)were intravenously injected 1 5 minutes before the end of surgery.Each patient was given PCIA,with solution including oxycodone 0.8 mg/kg plus FA 4 mg/kg plus ondansetron 8 mg plus 0.9% NaCl (1 50 ml)in group O and fentanyl 8 μg/kg plus FA 4 mg/kg plus ondansetron 8 mg plus 0.9% NaCl (1 50 ml)in group F.The coughing and resting visual analogue scale (VAS), Ramsay score at 2,6,12,24,36 and 48 hours after operation,complications,the times of patient controlled pressing and requirement for rescue analgesic were evaluated.Results Compared with group F, the resting and coughing VAS at 2, 6, 12, 24, 36 and 48 hours after operation, requirement for rescue analgesic,the incidence of nausea and vomiting and the times of patient con-trolled pressing were significantly lower in group O (P <0.05).There was no significantly difference in the Ramsay score.Conclusion It is effective that the patients undergoing thoracic surgery used the PCIA of oxycodone combined FA to control the postoperative pain, and analgesic effect more excellent than fentanyl combined FA,and with fewer side effects.
