Summary
Managing post-surgery discomfort is key to healing. Researchers investigated how different Esketamine doses impact recovery after thyroid surgery. They found that specific Esketamine doses significantly improved overall Recovery quality, reduced Postoperative pain and coughing, and supported better Emotion. A moderate dose (0.25 mg/kg) offered optimal benefits, including faster recovery and stable vital signs, without increased adverse reactions. This suggests a promising path for enhanced patient comfort and well-being.
Abstract
This study aims to the combination of remimazolam toluene sulfonate and esketamine hydrochloride in reducing postoperative complications and improving recovery outcomes in thyroid surgery patients. One hundred twenty patients undergoing radical thyroidectomy were randomly assigned to four groups: control group (Group C) and three esketamine groups (Groups S1, S2, S3). Before peeling, groups S1, S2, and S3 were administered with 0.15, 0.25, and 0.35 mg/kg of esketamine via slow intravenous injection, respectively. The primary outcomes was recovery quality (QoR-15). Secondary outcomes included postoperative pain (NRS scores), incidence of coughing (Minogue score), hemodynamic stability, emotional recovery (HADS scores), extubation time, adverse reactions, and sufentanil consumption. Baseline data showed no significant differences (p > 0.05). Pain and HADS scores were significantly lower in Groups S2 and S3 (p 0.05). Esketamine at doses of 0.25 mg/kg/h and 0.35 mg/kg/h improves recovery, reduces pain and coughing, and maintains hemodynamic stability. A dose of 0.25 mg/kg/h offers optimal clinical benefits with faster recovery.
