ABSTRACT
Objective To explore the value of ultrasound-guided balloon control technique in abdominal aorta for reducing intraoperative hemorrhage in high-risk placenta previa undergoing cesarean section.Methods From Aug 2013 to Oct 2017,40 cases were admitted,among them,16 cases were treated with ultrasound-guided towed balloon prophylactic control technique of abdominal aorta (the study group) before cesarean,and 24 cases did not receive balloon occlusion (the control group) during the cesarean.Clinical data were compared between the two groups.Results The time used for uterine suture (t =10.34,P =0.01),the amount of intraoperative blood loss (t =9.51,P =0.01) and blood transfusion (t =3.41,P=0.005)in the two groups were all statistically different.While the differences in PT (t =1.02,P =0.32),ALT (t =0.54,P =0.59),AST(t =0.91,P =0.37),creatinine(t =0.75,P =0.46) were not statistically significant between the two groups.Conclusion Ultrasound-guided abdominal aortic balloon control technique can reduce the blood loss significantly in cesarean section with high-risk placenta previa.
ABSTRACT
Objective To explore the value of topical pharyngeal anesthesia combined with deep sedation anesthesia in patients undergoing painless gastrointestinal endoscopy examination.Methods One hundred and fifty patients were randomly divided into test group and control group,each group 75 patients.Before the examination the patients of test group were sprayed throat 1％ tetracaine three times,the patients of control group were not performed throat spray.All patients were given intravenous midazolam 1.0 mg before the examination,then all patients were given intravenous fentanyl 0.05 mg and intravenous injection of propofol when BIS was 55-65,the microscopy was given.If the patients had somatic reaction or BIS ＞ 70,additional propofol 0.3-0.5 mg/kg.The blood pressure (BP),heart rate (HR),venous oxygen saturation (SpO2),the dose of propofol and side effects were observed.Results The anesthetic effects:excellent 59 cases,mild good 15 cases,no good 1 case in test group,excellent 53 cases,mild good 19 cases,no good 3 cases in control group,there was no significant difference (P ＞ 0.05).The level of SpO2,HR,MAP before anesthesia,during operation and after operation between two groups had no significant difference(P ＞ 0.05).The induction time and recovery time of anesthesia,the dose of propofol between two groups had no significant difference (P ＞ 0.05).The rate of restlessness,bucking,respiratory depression between two groups had no significant difference(P ＞ 0.05).In test group,pharyngeal portion unwell 37 cases,nausea 24 cases,tension 49 cases,and in control group was 0,0,12 cases,there was significant difference (P ＜ 0.05).Conclusions The use of deep sedation anesthesia with midazolam-fentanyl-propofol can not reduce the incidence of cough,respiratory depression and other side effects,but can increase the rate of pharyngeal portion unwell and nausea.The clinical value is limited.
