The Effect of Combined Bilateral Infraorbital and Infratrochlear Nerve Block in Nasal Surgeries

Overview

The aim of the study is to assess the efficacy of adding a pre-emptive combined bilateral infraorbital and infratrochlear nerve blocks with bupivacaine 0.25% in decreasing intraoperative and postoperative analgesics consumption and maintaining intraoperative hemodynamic stability during nasal surgeries.

Perioperative pain management is one of the most important issues of most surgical procedures. The goal of every pain management technique is to reduce or eliminate pain and discomfort with minimum side effects (Garmella and Cellini, 2012). Nasal surgical procedures are associated with a high incidence of emergence agitation leading to severe complications such as bleeding and delayed recovery which increase the hospital stay (Kim et al., 2015). Although the cause of emergence agitation is not well established, Pain in the immediate post-operative period is one of the significant risk factors for emergence agitation. Multiple analgesic interventions are applied to the patient before, during and after surgery prevent these complications (Gray et al., 2018). The most utilized analgesic interventions are combinations of narcotic and non-steroidal anti-inflammatory drugs. However, they are associated with gastrointestinal and neurological side effects which cause discomfort to the patient and affect surgical recovery profile (Çelik et al., 2018). Therefore, the utility of combining regional nerve block with general anesthesia has been popularized in clinical practice to provide improved perioperative analgesia, decreased narcotic consumption and enhanced emergence and recovery characteristics (Mariano et al., 2009; Ibrahim et al., 2018). The infraorbital nerve (ION) is a branch of the maxillary part of the trigeminal nerve. This nerve innervates the skin of the nose and septum mobile nasi. The infratrochlear nerve (ITN) innervates the root of the nose and is an extraconal branch of the nasociliary nerve, which is a branch of the ophthalmic portion of the trigeminal nerve (Choi et al., 2019). Although these nerve blocks are simple and easy to use with few complications, there are limited reports that suggest combined bilateral infraorbital and infratrochlear nerve blocks to be effective to facilitate pain management and reduce anesthetic agent consumption and perioperative dose of narcotics in nasal procedures (Cekic et al., 2013; Boselli et al., 2016).
