Role of Dexmedetomidine as monitored anaesthesia care in ENT local surgeries

Abstract

Analgesia and sedation are usually required for the comfort of all patients and surgeons during any surgery, particularly ENT surgery done under local anesthesia.We conducted study on 30 adult ASA grade I/II patients of either sex posted for various elective ENT surgeries under LA and monitored anesthesia care. Patients received IV dexmedetomidine infusion of 1mcg/kg over 10 min followed by 0.2mcg/kg/h during surgery. Sedation was maintained to keep Ramsay Sedation Score (RSS) to 3. Surgery was performed under LA. Intra operatively, if required, patients were given rescue analgesic fentanyl 1mcg/kg and rescue sedative midazolam 0.01mg/kg. Patients’ vital parameters (PR, BP, SPO2, ECG), VAS and sedation scores were recorded every 10 min. Post operatively all patients were interviewed to assess their satisfaction score about the technique. Surgeons were also asked for their opinion to assess their satisfaction about sedation technique.We found that:1.Surgeons’ and patients’ satisfaction score were better2.8 patients required rescue LA infiltration. 3.Number of patients requiring rescue analgesic and rescue sedative medication was 4 and 1 patient respectively.4.None of the patients in both the groups had any complications requiring active treatment.
