Effects of general anesthesia combined with superficial cervical plexus block anesthesia on intraoperative thyroxine levels and postoperative cognitive health in patients undergoing thyroid surgery

Anesthesia combined with superficial cervical plexus block anesthesia

Abstract

Objective: The aim of this investigation was to analyse whether general anaesthesia combined with superficial cervical plexus block anaesthesia affected intraoperative thyroxine levels and postoperative cognitive health in thyroid operation patients. Methods: A total of 106 patients who underwent thyroid surgery in our hospital between March 2020 and June 2020 were chosen and split into single general anaesthetic groups and compound anaesthesia groups with 53 patients. Patients undergoing thyroid surgery were given preoperative single-general anaesthesia, while patients were given general anaesthesia coupled with superficial cervical plexus block anaesthetic intervention in the composite anaesthesia group. The quality of the patients' awakening after surgery in the two groups was evaluated by analyzing the thyroxine levels before anesthesia (T0), 1 min, (T1), and 24 h after surgery (T2) to evaluate the pain condition and cognitive function before anesthesia (T0), 1 min, (T1), and 24 h after surgery (T2), and the incidence of adverse intraoperative and postoperative effects was recorded in the two groups. Results: Participants in the combination anaesthetic group exhibited reduced spontaneous breathing recovery time, directional force recovery time, and time to extubation and intubation compared to patients in the single general anaesthetic group (P< 0.05). At T1 and T2, the compound anaesthesia group had greater levels of FT3, FT4, T3, T4, and TSH than the single general anaesthetic group (P <0.05). At T1, compared with the single general anesthesia group, the composite anesthesia group had lower pain and cognitive scores (P < 0.05). At T2, compared with the single general anesthesia group, the composite anesthesia group had lower pain and cognitive scores (P < 0.05) and had greater levels of FT3, FT4, T3, T4, and TSH than the single general anaesthetic group, The composite anaesthesia group showed a decreased incidence of postoperative adverse events with statistical significance (P< 0.05) than the single general anaesthesia group. Conclusion: The use of general anaesthetic combined with superficial cervical plexus block anaesthesia in patients undergoing thyroid surgery has been demonstrated to be more beneficial, with less severe effects on patient thyroid function and reduced pain and cognitive gains.
