Efficacy and Safety of Continuous Paravertebral Block after Minimally Invasive Radical Esophagectomy for Esophageal Cancer

Abstract EN

Objective.

To compare the effects of continuous paravertebral block analgesia and patient-controlled intravenous analgesia after minimally invasive radical esophagectomy for esophageal cancer and their effects on postoperative recovery.

Methods.

A retrospective analysis was performed among 233 patients who underwent minimally invasive esophageal cancer radical operation and met the requirements, including 87 patients (group C) who were successfully placed with a continuous paravertebral block device under direct vision and 146 patients (group P) who used a patient-controlled intravenous analgesia device.

Visual analogue pain score (VAS) at rest and in motion for 1, 3, 6, 12, 24, 36, and 48 hours after awakening, incidence of adverse reactions of the two analgesic methods, occurrence of pulmonary complications after operation, use of emergency analgesics, and hospital stay after operation was recorded.

Results.

The VAS scores of group C in resting and active state at 1, 3, 6, 12, 24, 36, and 48 hours after operation were significantly lower than those of group P (P<0.001).

The incidence of adverse reactions, pulmonary complications, and the use of emergency analgesics in group C were lower than those in group P (P<0.05).

The hospitalization time of group C was significantly shortened, and the satisfaction degree of group C was significantly higher than that of group P (P<0.05).

Conclusion.

Paravertebral block is safe and effective for patients undergoing minimally invasive radical esophagectomy.

The incidence of adverse reactions and complications is lower, and the satisfaction of postoperative analgesia is higher, which is beneficial to the rapid recovery of patients after operation.
