Abstract:
Objective To investigate the effects of supreme laryngeal mask airway (SLMA) and endotracheal intubation on the elderly hypertensive patients treated with knee arthroplasty. Methods Forty cases of elderly hypertensive patients ASA Ⅰ-Ⅲ treated with knee arthroplasty in our hospital were selected and randomly divided into laryngeal mask airway group (group LMA)and endotracheal intubation (group TT),20 cases for each group.The same protocol for induction and maintenance of general anesthesia was used.After the patients entering,the changes of SpO2 and ECG were performed continuous noninvasive monitoring and SBP,DBP and HR were performed con-tinuous invasive monitoring.SBP,DBP and HR of two groups were recorded at different time points:before anesthesia induction (T0 ,based value),at intubation immediate (T1 ),5 mins after intubation (T2 )and 1 5 mins after intubation (T3 ).At the same time,the content of cortisol (Cor),atrial natri-uretic peptide (ANP)and the concentration of epinephrine (E)and norepinephrine (NE)were meas-ured at the corresponding time points above.Results Compared with T0 ,SBP and DBP at T1-T3 in group LMA were decreased(P <0.05 or P <0.01);SBP and DBP at T1 in group TT were increased while decreased at T2 ,T3 ,HR at T1 were increased(P < 0.05 or P < 0.01 ).Compared with group LMA,SBP and DBP at T1-T3 and HR at T1 ,T2 in group TT were increased (P <0.05 or P <0.01). Compared with T0 and group LMA,the content of E,NE and Cor at T1-T3 increased(P <0.05 or P <0.01).The level of ANP in both groups at T1-T3 were higher than those at T0 ,and group TT were higher than group LMA(P <0.01).Conclusion Compared to endotracheal intubation,SLAM can ef-fectively reduce the stress reaction of elderly hypertensive patients treated with general anesthesia in knee arthroplasty.
