Effectiveness of Intravenous Influence of Lidocain at Analgeesia After Video-Assisted Toraccoscopic Lobectomy

Abstract

Objective: Effect of perioperative intravenous lidocaine infusion after video-assissed toraxoscopic lobectomy. Materials and methods. 90 patients who underwent lobectomy with a video assisted thoracoscopic method were examined. In the first group (n = 30) for analgesia, intravenous infusion of lidocaine was used, in the second group (n = 30) - narcotic analgesics, in the third group (n = 30) epidural analgesia was used. An evaluation of the extubation time and the severity of the perspiratory response to the endotracheal tube was performed. The intensity of the postoperative pain syndrome was assessed on a 10-point visual analogue scale every 15 minutes for an hour, then every 4 hours after the first day. In all groups, during the first 24 hours, the consumption of narcotic analgesics was recorded, as well as the frequency of postoperative nausea and vomiting and the need for rehabilitation bronchoscopy. Results. The time of extubation in patients of the 1 st group was significantly greater than in the patients of the 2 nd and 3 rd groups. In patients of the 1 st group, the severity of the pressor response to extubation was significantly lower. The strength of pain in rest and motion, as well as the overall postoperative need for analgesics (promedol) were significantly lower (30.1 ± 2.25 mg and 51.1 ± 9.16 mg compared to 122.2 ± 14.18 mg, in groups of epidural analgesia and lidocaine group.In the postoperative period, there was a significantly lower level of postoperative nausea and vomiting in patients of Group I. The need for sanation PBS was noted in 2 (6.7%) patients in Group 1 and 5 (16.7%) patients in Group 2. In patients of the 3rd group, sanation bronchoscopy was not performed. Conclusion. An intravenous infusion of lidocaine at anesthesiology maintenance operations on light has a marked analgesic effect, which by its severity inferior epidural block, but greater than the systemic administration of narcotic analgesics, has opiodsberegayuschim effect, reduces the incidence of postoperative nausea and vomiting, is not accompanied by clinical signs of systemic local anesthetic toxicity. Infusion of lidocaine as a method of analgesia can be utilized in the case where the execution epidural impossible or not desirable.
