Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

transverse quadratus lumborum block

The patients will receive the transmuscular quadratus lumborum block before surgery using the transverse scan, in-plain, posterior to anterior approach. 0.6ml/kg 0.375% ropivacaine is injected when the correct needle location is confirmed.

Group Type ACTIVE_COMPARATOR

transverse scan, in-plane, posterior- anterior quadratus lumborum block

Intervention Type PROCEDURE

transverse scan, in-plane, posterior- anterior quadratus lumborum block The patients will receive the transmuscular quadratus lumborum block before surgery using the transverse scan, in-plain, posterior to anterior approach. 0.6ml/kg 0.375% ropivacaine is injected when the correct needle location is confirmed.

longitudinal quadratus lumborum block

The patients will receive the transmuscular quadratus lumborum block before surgery using the paramedic sagittal longitudinal scan, in-plain, caudal-cephalic approach.0.6ml/kg 0.375% ropivacaine is injected when the correct needle location is confirmed.
