Clinical study of low-dose light specific gravity intraspinal anesthesia and nerve block anesthesia for hip replacement
Objective To evaluate the clinical effect of low-dose light specific gravity intraspinal anesthesia and nerve block anesthesia for hip replacement.Methods 130 patients with orthopedic hip replacement were divided into nerve block anesthesia group(group N)and low-dose light specific gravity intraspinal anesthesia group(group C)by random number table method,each with 65 cases.Group N received nerve block anesthesia during surgery,and group C received low-dose light specific gravity intraspinal anesthesia during surgery.The anesthetic effect indicators,occurrence of complications and hemodynamic indexes of the two groups were compared.Results The onset time of anesthesia,the duration of sensory block and the duration of motor block in group C were(3.56±1.03),(24.86±5.58)and(76.85±20.24)min,which were obviously shorter than(16.58±2.54),(435.29±50.68)and(298.67±50.62)min in group N,and the difference was statistically significant(P<0.05).There was no significant difference in incidence of complications between the two groups(P>0.05).There was no significant difference in mean arterial pressure(MAP)and heart rate(HR)between the two groups before anesthesia and 30 min after surgery(P>0.05).MAP and HR of group N after surgery were(89.25±10.76)mm Hg(1 mm Hg=0.133 kPa)and(76.34±5.64)beats/min,which were significantly lower than(93.45±11.02)mm Hg and(78.91±5.82)beats/min of group C.The difference was statistically significant(P<0.05).Conclusion The effect of low-dose light specific gravity intraspinal anesthesia in hip replacement is better than that of nerve block anesthesia.It can stable patients'hemodynamics and will not increase the occurrence of perioperative complications.It is worthy of clinical application.
