ABSTRACT
Objective:
To investigate the value of atropine administration before tracheal intubation under general anesthesia in the elderly patients undergoing endobronchial ultrasound-guided transbronchial needle aspiration(EBUS-TBNA)biopsy.Methods:
This was a case-control study.A total of 87 elderly hospitalized patients receiving chest enhanced CT test suggesting the risk of lung cancer with enlargement of mediastinal lymph nodes in 7 regions were scheduled to undergo endobronchial ultrasound-guided transbronchial needle aspiration(EBUS-TBNA)biopsy under general anesthesia.The patients were randomly divided into two groups by flipping a coin the atropine group(n=40)and the control group(n=47). The indicators for evaluating the application values of atropine included preoperative, intra-operative and postoperative systolic blood pressure(SBP), diastolic blood pressure(DBP), heart rate, oropharyngeal and airway secretion volume, oxygen saturation, operation time, positive diagnosis rate and postoperative adverse reactions.Results:
SBP and DBP were lower in the atropine group than in the control group before endotracheal intubation(131.7±15.3 mmHg vs.140.7±13.7 mmHg, 79.1±7.6 mmHg vs.85.6±7.4 mmHg, t=2.885 and 4.061, P<0.05). There was no significant difference in SBP and DBP 10 min after endoscopic operation and 10 min after tracheal extubation between the atropine group versus the control group(SBP 109.1±11.2 mmHg vs.105.0±12.2 mmHg, 136.9±23.0 mmHg vs.129.9±11.2 mmHg, DBP 66.9±7.5 mmHg vs.68.0±8.3 mmHg, 77.6±10.9 mmHg vs.78.5±6.4 mmHg, t=-1.617, 0.687, -1.751 and 0.448, P>0.05). There was no significant difference in HR between the two groups before endotracheal intubation( t=1.416, P>0.05), while HR was higher in the atropine group than in the control group 10 min after endoscopic operation and 10 min after tracheal extubation( t=-3.323 and -2.181, P<0.01 and P<0.05). The change rates of SBP and DBP were lower in the atropine group than in the control group 10 min after endoscopic operation and 10 min after tracheal extubation( t=7.947, -6.962, -3.187 and -3.232, P<0.01). The change rate of HR was lower in the atropine group 10 min after endoscopic operation and was higher 10 min after tracheal extubation than in the control group( t=-6.467 and -4.131, P<0.01). There were significant differences in the volume of oropharyngeal and airway secretions and fingertip oxygen saturation between the two groups before endotracheal intubation and 10 min after tracheal extubation( t=-2.334, 2.759, -3.314 and -2.767, P<0.01). The endoscopic operation time was less in the atropine group than in the control group with no statistically significant difference[(25.9±5.7)min vs.(26.4±4.7)min, t=0.391, P>0.05]. There was no significant difference in postoperative adverse reactions between the atropine group versus the control group(34 patients or 85.0% vs.43 patients or 91.5%, χ2=1.247, P>0.05).Conclusions:
The application of atropine before tracheal intubation under general anesthesia is beneficial to stabilizing the intraoperative blood pressure and heart rate, and can reduce the production of postoperative oropharyngeal and airway secretions in elderly patients undergoing endobronchial ultrasound-guided transbronchial needle aspiration biopsy.
