Brief Summary

Previous study reported that propofol binded to glutamate receptors in the hypothalamus and inhibits AVP release mediated by endogenous γ-aminobutyric acid, as well as directly inhibits the regulated calcium currents leading to normal neuronal depolarization and AVP release. However, there is no clinical data demonstrating the mechanism of propofol can induce transient DI by inhibiting the release of AVP from the hypothalamus when applied to humans. Remifentanil, binding to the μ-receptor or partly κ-receptor, have been used in total intravenous anesthesia combined with propofol, also reported inhibiting AVP relaese in both the hypothalamus (κ receptor mediator mechanism) and posterior pituitary (μ receptor mediator mechanism). However, the effects of anesthetics on water homeostasis during surgery have been not well established. Therefore, we aim to investigate the changes of intraoperative water homeostasis, and related hormones and osmolality in patients with propofol based total intravenous anesthesia due to neuromonitoring for spine surgery.

Conditions

Outcome Measures

Primary Outcomes (1)

  • The water homeostasis changes of patients during propofol based total intravenous anesthesia for neuromonitoring in spine surgery

    The amount of urine (polyuria standard\> 5 ml/kg/h) during surgery

    The change over time during surgery: baseline (before operation, T1), one hour after operation (T2), two hours after operation (T3), and three hours after operation (T4) - measure at four times

Secondary Outcomes (1)

  • Postoperative polyuria (or diabetes insipidus)

    At postoperative 24 hours and 48 hours

Study Arms (1)

A patient who need the spine surgery

A patient who go the propofol based total intravenous anesthesia due to intraoperative neuromonitorung for spine surgery

Procedure: A patient who need the cerebral artery aneurysm clipping surgery

Interventions

A patient who go the propofol based total intravenous anesthesia due to intraoperative neuromonitorung for unruptured cerebral artery aneurysm clipping surgery

A patient who need the spine surgery
