Abstract
|
|
|
Effrctive analgesia after elective thoracotomy can be provided by continuous extrapleural intercostal nerve block.
This study was designed to prove the effectiveness of continuous extrapleural intercostal nerve block. Twenty patients undergoing elective thoracotomy were randomized into two groups. Group I received lumbar epidural block(n=10) and group II
received
continuous extrapleural intercostal nerve block(N=10). Postoperative pain relief was assessed on Numeric Rating Scale(NRS) and recovery of pulmonary function was assessed by comparison of preoperatrive and postoperative FVC(Forced Vital
Capacity),
FEV1(Forced expiratory Volume in 1 second), VC(Vital Capacity). Arterial blood gas analysis(ABGA), vital signs and amount of additive analgesic were compared also. No significant difference was observed between the groups concerning these
parameters
mentioned above. Systemic complications, such as urinary retention(2/10) and weakness of lower extremity(2/10), occurred in group I but no complication occurred in group II.
We conclude tat continuous ext5rapleural intercostal nerve block is as effective as epidural block in pain relief and restoration of pulmonary mechanics with fewer comlications. Also because of it's ease and safetiness, this must be considered as
a
substitute of epidural block in routine use for thoracotomy pain relief. (Korean J Thoracic Cardiovas Surg 1993;26:781-6)
