Background and aims: Enhanced recovery after surgery (ERAS) has been applied in various laparoscopic procedures. Intravenous lidocaine (IVL) infusion is used for laparoscopic procedures as a part of ERAS protocols. The study aimed to evaluate the role of IVL infusion in enhanced bowel recovery after laparoscopic renal surgeries.
Material and methods: A randomized, double-blind, placebo-control trial was conducted on 80 patients (with American Society of Anesthesiologists physical status I-II) who presented for laparoscopic renal surgeries under general anesthesia. The study period was from Oct 2018 to Sept 2019. By computer-generated codes, patients were randomly divided into two groups: L (lidocaine) and C (control). Group L received an intravenous (IV) bolus (1.5 mg/kg) of 2% lidocaine over 2 min, followed by an IV lidocaine infusion at the rate of 1.5 mg/kg/h until skin closure. Group C received the same volume of bolus followed by normal saline infusion. Patients were monitored for bowel functions, total hospital stay, and total analgesic consumption. Student's t-test and Chi-square test were used for quantitative data and occurrence of events, respectively. P <0.05 was considered to be statistically significant.
Results: First bowel sound, flatus, and defecation occurred in 16.4 ± 2.50, 26.7 ± 9.02, and 39.1 ± 6.31 h, respectively, in group L and 18.2 ± 2.90, 32.3 ± 3.11, and 43.3 ± 4.22 h, respectively, in group C (P = 0.006, 0.001, and 0.01, respectively). Total hospital stay was 4.0 ± 0.74 and 5.3±0.0.91 days in groups L and C, respectively (P < 0.001).
Conclusion: The present study concluded that IVL could enhance the bowel recovery and reduce total hospital stay after laparoscopic renal surgeries.
