简要总结
Our objective is to investigate the extent of cranial dermatomal spread of transmuscular quadratus lumborum block(TMQLB )when equal dosage(ml/kg) of local anesthetic are injected with the transverse versus an modified paramedian sagittal approach for patients undergoing laparoscopic adrenalectomy.
详细描述
The paramedian sagittal oblique transmuscular quadratus lumborum block(TMQLB )approach has been introduced to facilitate cranial spread by injecting the local in a caudal to cranial direction compared with the transverse approach. Currently, there are no data comparing the two techniques mentioned above with regards to extent of spread level. Our objective is to investigate the extent of cranial dermatomal spread of TMQLB when equal dosage(ml/kg) of local anesthetic are injected with the transverse versus an modified paramedian sagittal approach for patients undergoing laparoscopic adrenalectomy. In addition, the investigators wish to compare the performance time, caudal dermatomal spread of TMQLB and postoperative analgesia effect.

结局指标
主要结局
Cephalic sensory dermatomal spread
时间窗: 20 minutes after block performance]
The pinprick method at the midclavicular line was used to assess the extent of the dermatomal blockade, 20 minutes following the completion of the procedure by a person who was blinded to group allocation. The most cephalic dermatomal level that show a decreased pinprick sensation is recorded.A block failure was defined as the absence of any demonstrable sensory block 20 minutes after performance of the block.
