Effect of various uses of propofol on the upper gastrointestinal endoscopy / 中南大学学报(医学版)

OBJECTIVE@#To investigate the efficacy and security of different uses of propofol on the sedation during the upper gastrointestinal endoscopic procedures.@*METHODS@#Four hundred patients who underwent gastroscopy received midazolam and propofol as sedation. Patients were divided to 4 groups with different intervals between midazolam and propofol: Group A and D with the interval of 30 seconds to 1 minute, Group B and C with 3 to 5 minute interval. All patients were premedicated with midazolam and propofol at 16 approximately 25 mg/10s (Group A and B) and 6 approximately 7 mg/10s (Group C and D).@*RESULTS@#The doses of propofol of Group A,B,C, and D were (111.90+/-22.43),(102.20+/-15.99),(73.05+/-13.08) and (80.90+/-17.36)mg respectively, with significant difference(P<0.01). The time of return to consciousness decreased markedly in Group C and D [(9+/-1), (10+/-2)min ], and that of Group A and B was [(14+/-5), (13+/-3)min ]. There was significant difference between Group C, D and Group A, B(P<0.01).@*CONCLUSION@#The dose of propofol and the time of return to consciousness depend on the rate of administration and the interval between midazolam and propofol. Appropriate rate and interval can produce safer and more effective sedation for the upper gastrointestinal endoscopic procedure.

Two-stage administration sedation method for gastroscopy in hypoxia predisposed patients / 中南大学学报(医学版)

OBJECTIVE@#To explore the safety and the efficacy of two-stage administration sedation method (with propofol plus midazolam) in the analgesia gastroscopy for hypoxia predisposed patients.@*METHODS@#Sixty-four hypoxia predisposed patients (with snore or expectoration) were divided into two groups and received sedation respectively with two-stage administration method and routine continuum administration method before gastroscopy. We analyzed the alteration of SBP, DBP, SpO2, sedation level, the degree of pharyngeal malaise, recovery time, dose of propofol,the lethe degree of upset, and procedure of gastroscopy to evaluate the safety and the efficacy of the two methods in the analgesia gastroscopy for hypoxia predisposed patients.@*RESULTS@#Compared with routine continuum administration sedation method, two-stage administration sedation method had little influence on SpO2, so it reduced the accident of respiratory arrest (P 0.05), and the lethe degree of gastroscopy procedure in two-stage administration method group was significantly lower than that of routine continuum adminis- tration method group (P <0.01).@*CONCLUSION@#The two-stage administration sedation method is a new effective and safe sedation method for gastroscopy in the hypoxia predisposed patients.
