简要总结
Patients's demographics and perioperative factors affect the occurrence of hypotensive bradycardic events in the patients undergoing arthroscopic shoulder surgery in the sitting position under interscalene block.
详细描述
Patients' age, Side of the block,Horner's syndrome, the degree of blockade, preoperative fasting time and fluid administration volume, waiting time for sitting position after the block, intraoperative use of opioids and antihypertensives, and change of heart rate variability before the block and after sitting position affect the occurrence of hypotensive bradycardic events in the patients undergoing arthroscopic shoulder surgery in the sitting position under interscalene block.

结局指标
主要结局
Patient's age and gender, fasting time, administered volume, blood pressure, and heart rate variability
时间窗: Prior to ISBPB
Patients'age and gender, preoperative fasting time and volume of fluid administered, pre-block mean arterial pressure and heart rate, logarithmically transformed low frequency, high frequency, and total power of heart rate variability
次要结局
- Side of the block, volume of local anesthetics used, number of patients having Horner's syndrome, hoarseness, and subjective dyspnea, degree of dermatomal and motor blockade(20 minutes after the end of local anethetics injection)
- Waiting time for sitting position, heart rate variability, mean arterial pressure, heart rate, frequency of antihypertensives and opioids use, and onset of hypotensive bradycardic events(after the sitting position (expected average of 2 hours including surgery readiness time and duration of surgery))
