ABSTRACT
Objective To observe the effect of propofol infusion on the side effects of carboplatin and trometamol at different plasma target concentrations in cesarean section.Methods From January 2016 to October 2017,a total of 184 cases of cesarean section pregnant women in the People's Hospital of Quzhou were selected for prospective study.They were divided into A group ,B group,C group and control group (N group) according to random number table method,with 46 cases in each group.The A,B,C three groups were target -controlled infusion of propofol,the concentrations were 0.8μg/mL,1.2μg/mL,1.6μg/mL,respectively,while N group was infused 0.9%sodium chloride injection at the rate of 0.5mL· kg-1· h-1.The operative time,intraoperative blood loss,fluid replacement,elevated blood pressure,decreased blood pressure ,the incidence of tachycardia and adverse reactions were compared among the four groups.Results The operation time of the four groups were (46.65 ±5.32) min, (49.21 ±4.75)min,(48.74 ±4.28) min,(49.76 ±5.25) min,respectively,the differences were not statistically significant(F＝1.501,P ＞0.05).The volume of intraoperative blood loss in the four groups were (425.66 ± 39.54)mL,(428.71 ±41.03)mL,(427.96 ±41.55)mL,(431.56 ±42.35)mL,respectively,the differences were not statistically significant(F＝1.882,P＞0.05).The fluid replacement in the four groups were (884.59 ±51.22)mL, (879.20 ±47.63)mL,(883.59 ±50.14)mL,(896.33 ±50.23)mL,respectively,the differences were not statistically significant(F＝1.634,P＞0.05).The satisfaction rate of sedation in B group was 91.30%,which was significantly higher than 58.70%in A group and 30.43%in C group(Z＝91.428,P＜0.05).The incidence rates of cardiovascular events in B group and C group were significantly lower than those in A group (all P＜0.05),which in B group were lower than those in C group(all P＜0.05).There were no statistically significant differences in chest tightness ,head-ache,facial flushing incidence in the three groups (χ2＝3.450,4.816,5.396,all P＞0.05).The incidence rates of nausea and vomiting in B group were 8.70%and 4.35%,respectively.The incidence rates of nausea and vomiting in C group were 8.70%and 2.17%,respectively,which were significantly lower than those in A group (26.09% and 19.57%)(χ2＝7.485,10.405,all P＜0.05).Conclusion Targeted infusion of propofol at 1.2 μg/mL can effec-tively prevent the side effects of cesarean section carduvastatin trometamol with good sedative effect .
ABSTRACT
Objective To evaluate the feasibility of induction with sevoflurane-midazolam-remifentail for tracheal intubation without muscle relaxants in neck brake patients.Methods Forty ASA Ⅰ or Ⅱ patients with cervical spine fracture with dislocation,aged 13-68 yr,scheduled for surgery under general anesthesia,were enrolled in this study.Anesthesia was induced with iv injection of midazolam 0.03 mg/kg and inhalation of 5%sevoflurane through a mask.Sevoflurane was inhaled at the initial concentration of 5%,followed by decrement of 1% every 30 s until 3%.When the eyelash reflex disappeared,remifentanil 2 μg/kg was injected slowly over 45s and 30 s later sevoflurane inhalation was stopped.The patients were mechanically ventilated after tracheal intubation.The time of disappearance of eyelash reflex was recorded.The intubation condition was evaluated using VibyMogensen score.Results All patients were successfully intubated at the first attempt.The time period from sevoflurane inhalation to disappearance of eyslash reflex was(69 ± 4)s.Coughing occurred in 3 cases during intubation.The satisfactory intubation conditions were found in 100% of cases.SpO2 ＞ 95% in all patients.BlS was maintained at 45-55 during the period(before intubation until 3 min after intubation).Conclusion Induction with sevoflurane-midazolam-remifentail is rapid and smooth,provides good conditions for intubation and can be applied to tracheal intubation without muscle relaxants in neck brake patients.
