ABSTRACT
Based on the International Federation of Nursing Anesthetists (IFNA) education and training base, our hospital has built a training base for anesthesia specialized nurses in Nanjing from the following aspects: the application for training base of anesthesia specialized nurses, the qualification and examination of students' and teachers' qualification, the settings of training curriculum, the examination contents and methods, and the evaluation of post-training effect. This article summarizes the construction experience of this base, therefore, providing support and standard for the training of anesthesia specialized nurses.
ABSTRACT
Objective To evaluate the effect of sevoflurane anesthesia on left ventricular synchroni?zation in patients undergoing coronary artery bypass grafting ( CABG ) . Methods Twenty?six patients of both sexes, aged 45-75 yr, with body mass index of 19-30 kg∕m2 and body surface area 1.4-2.0 m2 , of American Society of Anesthesiologists physical status Ⅱ or Ⅲ and New York Heart Association class ⅡorⅢ, undergoing elective CABG with cardiopulmonary bypass, were divided into 2 groups using a random number table: control group ( group C, n=11) and sevoflurane group ( group S, n=15) . After induction of general anesthesia, the patients were endotracheally intubated and mechanically ventilated. Anesthesia was maintained with iv infusion of propofol 4-6 mg·kg-1 ·h-1 , remifentanil 0. 2-0. 3 μg·kg-1 ·min-1 and cisatracurium 0.10-0.15 mg·kg-1·h-1, and intermittent iv boluses of fentanyl 0.5 μg∕kg, and bis?pectral index value was maintained at 40-60. In group S, sevoflurane ( end?tidal concentration: 2.05% for 45-49 yr, 1.80% for 50-59 yr, 1.60% for 60-75 yr) was inhaled for 30 min starting from 15 min after termination of cardiopulmonary bypass, followed by 30 min washout. The parameters of cardiac function were monitored using transesophageal echocardiography. After induction and before sternotomy, immediate?ly before sevoflurane inhalation, at 30 min of sevoflurane inhalation, and at 30 min of washout, heart rate, mean arterial pressure, central venous pressure, pulmonary artery occlusion pressure, cardiac output, left ventricular ejection fraction, standardized standard deviation of time to peak systolic longitudinal strain of R?R interval ( Tssl?SD) of 17 left ventricular segment, and standardized standard deviation of time to peak systolic circumferential strain of R?R interval ( Tssc?SD) of 16 left ventricular segment were recorded. Re?sults Cardiac output and left ventricular ejection fraction were within in the normal ranges in the two groups. Compared with group C, heart rate was significantly decreased at 30 min of sevoflurane inhalation and 30 min of washout, and mean arterial pressure, cardiac output and left ventricular ejection fraction were significantly decreased at 30 min of sevoflurane inhalation in group S (P0.05) . Conclusion Sevoflurane anesthesia has no marked effect on the left ventricular synchronization in patients undergoing CABG.
