The Effect Of The Head Elevation And Hypsokinesis With The Extraction Angle Of 60° On The Stress Response In Patients

Objective:To observe the effect of the head elevation and hypsokinesis with the extraction angle of 60°on the stress response in patients.Methods:Ninety patients who were treated with the great saphenous vein high ligation surgery were divided into three groups according to the random number table method,each group had thirty patients.Patients in group A with supine position,the angle of tracheal extubation was 90 °(90 ° from the angle of the ground),patients in group B with supine position,the angle was 60 °(60 ° from the angle of the ground),patients in group C with head selevation and hypsokinesis,the angle was 60 °.SBP,DBP,HR and extubation force were recorded at the end of the operation(T0),1 minute before extubation(T1),1 minute after extubation(T2),5 minutes after extubation(T3),venous blood were collected at each time to measure plasma levels of adrenaline(AD),norepinephrine(NE)and cortisol(CORT),the occurrence of bucking,sore throat,hoarseness were observed.Results:The SBP,DBP,HR and plasma levels of AD,NE,CORT at T2 were significantly higher than those at T0 in all groups(P<0.05),while the SBP,DBP,HR and plasma levels of AD,NE,CORT at T3 were significantly higher than those at T0 in only group A and group B(P<0.05),the differences of those indicators between T3 and T0 had no statistical significance in group C.The SBP,DBP,HR and plasma levels of AD,NE,CORT at T2,T3 and the extubation force were significantly decreased in group B and group C compared with group A(P<0.05).Compared with group B,the SBP,DBP,HR and plasma levels of AD,NE,CORT at T2,T3 and the extubation force were significantly decreased in group C(P<0.05).The incidence of choking in group B[three cases(10.0%)]and group C[two cases(6.6%)]were significantly decreased than that in group A[twelve cases(40.0%)](P<0.05).Conclusion:The head elevation and hypsokinesis with the extraction angle of 60°can significantly reduce stress reaction in patients during the extubation.
