Abstract:Objective To investigate the effect of Dexmedetomidine combined with Pentazocine on restlessness and hemodynamics during general anesthesia recovery period in elderly patients.Methods A total of 150 elderly patients admitted to our hospital from January to December 2018 were selected as the research objects, and they were divided into group D+P (75 cases) and group P (75 cases) according to the random number table method.Patients in group D+P were anesthetized with Dexmedetomidine combined with Pentazocine, and patients in group P were anesthetized with Pentazocine.The heart rate (HR) and mean arterial blood pressure (MAP) at the completion of surgery (T1), tracheal tube extraction (T2), and 5 minutes after tracheal tube extraction (T3) were compared in the two groups, the incidence of adverse reactions in the two groups was observed,and the time of tracheal tube extraction and the first time of spontaneous respiration in the two groups of patients were recorded.Results The HR and MAP of patients in group D+P at T1-T3 were lower than those in group P, and the differences were statistically significant (P<0.05).The HR and MAP at T2 and T3 in group D+P were higher than those at T1,and the differences were statistically significant (P<0.05).The HR and MAP at T2 and T3 in group P were higher than those at T1, and the differences were statistically significant (P<0.05).The incidence rates of nausea, vomiting and agitation in group D+P were lower than those in group P, and the differences were statistically significant (P<0.05).The incidence rate of bradycardia in group D+P was higher than that in group P,and the difference was statistically significant (P<0.05).The time of tracheal tube extraction and the first time of spontaneous respiration in group D+P were shorter than those in group P, and the differences were statistically significant(P<0.05).Conclusion The use of Dexmedetomidine combined with Pentazocine during surgery in elderly patients has a low incidence of adverse reactions, hemodynamic stability can be guaranteed during the general anesthesia recovery period, and it can shorten the time of tracheal tube extraction and the first time of spontaneous respiration, which can be used as an important anesthesia method for elderly patients, and it is worthy of widespread application in clinic.
