Effects of Lidocaine Infusion on Quality of Recovery and Agitation After Functional Endoscopic Sinus Surgery

Effects of Lidocaine Infusion on Quality of Recovery and Agitation After Functional Endoscopic Sinus Surgery: Randomized Controlled Study

The essential anesthesia requirements for FESS include airway management, considerations for facilitating surgical access, provision of a clear and still surgical field for precision surgery, assuring quick and non-stimulating emergence from anesthesia, and fast-tracking patients for discharge. Postoperative agitation, although short-lived, is potentially harmful to both patients and recovery room staff, it has a potential for self-injury by removing intravenous catheters, tubing, oxygen masks and nasal packs. Furthermore, very agitated patients can pose an immediate danger to operating theatre staff.

Lidocaine is an amino amide-type short-acting local anesthetic (LA). It has a short half-life, and a favorable safety profile, and is therefore the LA of choice for continuous IV administration, it has analgesic, and anti-inflammatory effects that are induced by reduction of cytokines production through inhibition of neutrophil activation, and the analgesia may persist even after plasma concentration reduction. It can blunt the pressor response to endotracheal intubation also systemic lidocaine was effective in producing controlled hypotension.
