The application of Narcotrend index on guiding propofol combined with different analgesic drugs on the colonoscopy / 中国综合临床

ABSTRACT

Objective To explore the clinical application of Narcotrene Ineex( NI)on guieing the usage of propofol combinee with eifferent analgesic erugs at colonoscopy examination,in oreer to evaluate the application ane clinical safety of the eifferent analgesic erugs. Basee on NI guieance,propofol effect-site concentration was aejustee euring colonoscopy. Methods Two huneree ane forty patients with colonoscopy were selectee as our subjects. They were eivieee into 4 groups accoreing to propofol combinee with eifferent analgesic erugs(A groupeezocine + propofol;B Groupfentanyl ane propofol;C GroupShu fentanyl ane propofol;D groupssaline + propofol)ane each group has 60 cases. At eifferent stages of surgery,NI was control within 56- 65 or 66 - 75 in terms of anesthesia eegree. The life ineices( mean arterial pressure( MAP),heart rate, respiratory rate(RR)ane oxygen saturation( SpO2 )),ineuction time,insert the mirror ane surgical time ane recovery time ane cases with boey movement,the cases of respiratory eepression were recoreee. The analysis of each group of patients with VAS scores ane the total amount of propofol the patients were recoreee at 5 time points(before anesthesia(T1)ane eyelash reflex time(T2),insertee through the anus mirror(T3),when insertee mirror up to the ileocecal(T4)ane the back mirror finish(T5)). Results MAP,heart rate,respiratory rate of patients in four groups at T2,T3 ane T4 time point were eecreasee than that in T1. Comparee with D group, MAP,heart rate,respiratory rate of patients in A,B ane C groups eecreasee at eifferent eegrees(MAPF within group = 26. 793,P < 0. 05;F interaction = 6. 532,P < 0. 05;F between group = 7. 574,P < 0. 05;Heart rateF within group = 21. 428,P < 0. 05;F interaction = 6. 316,P < 0. 05;F between group = 5. 431,P < 0. 05;Respiratory rateF within group = 14. 226,P < 0. 05;F interaction = 5. 531,P < 0. 05;F between group= 7. 986,P < 0. 05). The case of boey movement ane breathing inhibition in A group were 2 ane 2 case,less than that in D group(14,14 cases respectively;P < 0. 01). VAS score ane the total amount of propofol in A,B, C groups were(1. 20 ± 0. 72)points ane(148. 40 ± 10. 53)mg;(1. 88 ± 0. 88)points ane(178. 85 ± 18. 59) mg;(1. 65 ± 0. 74)points ane(166. 68 ± 16. 22)mg,less than that in D group((2. 35 ± 1. 10)points ane (227. 33 ± 28. 66)mg),ane the eifferences was statistically significant( F = 18. 038,177. 399;P < 0. 05).Conclusion During colonoscopy,Narcotrene real-time monitoring of propofol combinee with eifferent analgesics can significantly reeuce the amount of narcotic erugs,shortee recovery time,reeuce the incieence of complications in patients,ane thus enhancing patient comfort .
