Tubeless Spontaneous Ventilation Anesthesia in Kidney Transplantation

The aim of this clinical trial is to compare the intraoperative use of neuromuscular blocking agents and other anesthetic drugs between tubeless spontaneous ventilation anesthesia (TSVA) and conventional endotracheal intubation (ETT) anesthesia in kidney transplantation. The study will also evaluate the safety, stability, and postoperative recovery associated with TSVA.

This trial is designed to address the following questions:

* Does TSVA reduce the intraoperative requirement for neuromuscular blocking agents and other anesthetic medications? * Does TSVA improve postoperative outcomes in kidney transplant recipients? * How do the intraoperative safety and stability of TSVA compare with those of ETT anesthesia?

Researchers will compare anesthetic drug consumption, intraoperative anesthetic performance, and postoperative recovery outcomes between the TSVA and ETT groups to determine whether TSVA can decrease anesthetic drug use and enhance patient recovery.

Participants will:

* Undergo a complete preoperative assessment * Receive kidney transplantation under TSVA or ETT anesthesia, with relevant intraoperative data recorded * Receive tubeless postoperative management, with documentation of pain scores, complications, and recovery of graft function * Be followed throughout their lifetime after discharge, providing long-term follow-up information
