Nerve Block, Transapical Beating-heart Septal Myectomy
Conditions
Brief summary
To retrospectively analyze the intraoperative and postoperative status of patients with hypertrophic cardiomyopathy undergoing TA-BSM, and to estimate whether paravertebral nerve block can improve postoperative pain for these patients.
Detailed description
Since conventional septal myectomy can be only assessed when the heart resumes beating, and the complications induced by cardiopulmonary bypass are inevitable, a novel transapical beating-heart septal myectomy (TA-BSM) has been invented, which provides real-time evaluation to guide resection while reducing surgical trauma. Postoperative pain after TA-BSM is unknown. Whether paravertebral nerve block can improve postoperative pain caused by TA-BSM is the objective of our study.
Interventions
PROCEDUREThoracic paravertebral block
Thoracic paravertebral block was performed before surgery

Secondary
| Measure | Time frame | Description |
|---|---|---|
| Postoperative pain score 2 | Day 7 after surgery and month 3 after surgery | Brief Pain Inventory(The degree of pain \[0 no pain to 10 very painful\] and the impact of pain on daily life function \[0 no impact to 10 very impact\]) |
| Physical recovery after surgery | Day 7 after surgery | Quality of recovery(Rating from 0 \[very poor\] to 150 \[excellent\]) |
| Complications | 24 hours and 48 hours after surgery | The incidence of nausea and vomiting |
| Perioperative information 1 | Immediately after the surgery | The usage of analgesic drug |
| Postoperative pain score 1 | 24 hours after surgery and and 48 hours after surgery | Visual Analogue Scale score(0-10 stands for the degree of pain, 0=no pain, 10=the worst pain ever) |
| Perioperative information 3 | P1= before induction, P2= 5 minutes after tracheal intubation, P3= before skin incision, P4= 5 minutes after skin incision, P5=5 minutes after placed the rib spreader | Heart reat |
| Perioperative information 4 | Immediately after the surgery | Duration of anesthesia |
| Postoperative information 1 | Postoperative in 24 hours | Extubation time |
| Postoperative information 2 | Postoperative in 48 hours | The usage of analgesic drug |
| Perioperative information 2 | P1= before induction, P2= 5 minutes after tracheal intubation, P3= before skin incision, P4= 5 minutes after skin incision, P5=5 minutes after placed the rib spreader | Mean arterial blood pressure |
