Clinical Trial Summary

The goal of this observational study is to learn about the effects of total intravenous general anesthesia with target controlled infusion and sevoflurane based balanced general anesthesia on hemodynamic parameters and cardiac enzyme levels in patients undergoing total abdominal hysterectomy.


Description:

Total intravenous anesthesia (TIVA) is a common anesthesia method used today as an alternative to inhalation anesthesia. Loss of consciousness is an important component of general anesthesia, in order to give the patient safe analgesia and not to remember any adverse events related to the operation. While the depth of anesthesia can be controlled by monitoring the minimum alveolar concentration (MAK) in the ventilator devices in the modern operating room , there was no more objective method than measuring the plasma level of drugs in intravenous anesthesia. The schemes created by the anesthetists according to plasma drug levels were used when administering total intravenous anesthesia. Target Controlled Anesthesia (TCI) devices on the other hand, are pumps that have been used more frequently recently and that can deliver the required blood concentration of a drug in bolus and infusion form according to pharmacokinetic models calculated with personal data. In TCI anesthesia, intravenous infusion of anesthetics provides a more stable drug concentration in the plasma and at the site of action compared to repeated bolus techniques. Thus, it is ensured that the results such as excessively high or excessively low administration of drugs are avoided and the drug remains in the therapeutic range. In inhalation anesthesia, anesthetic substances are absorbed from the alveoli, pass into the bloodstream and reach the brain. Tracheal intake of the anesthetic agents used in this method is rapid and the depth of anesthesia can be controlled. However , the patient should be monitored and followed up for complications . An ideal inhalation anesthetic has a minimal effect on the cardiovascular and respiratory systems and has no toxic effects on these systems. Due to these properties, the most commonly used anesthetic drugs for inhalation anesthesia today are isoflurane and sevoflurane. In terms of its cardiopulmonary effects, Sevoflurane is reported to provide faster and deeper anesthesia than other anesthetics. Aim: In this study, the researchers aim to compare the change of cardiac enzyme levels from baseline in patients undergoing total abdominal hysterectomy under general anesthesia with TCI anesthesia and sevoflurane based balanced anesthesia. Method: 140 patients who meet the inclusion criteria and signed informed consent will be included. All patients will be monitored with routine anesthesia monitoring and bispectral index (BIS), all parameters will be checked and recorded in 5 minute intervals throughout the operation. 70 patients will receive TCI-TIVA and 70 patients will receive sevoflurane based balanced anesthesia. Creatin kinase (CK), Creatin kinase - myoglobin binding (CK-MB), Troponin I values will be determined 3 times; before the induction of anesthesia, after the extubation of the patient at the end of the operation and 8 hours after the end of the operation. Statistical analysis: It is planned to use 'Independent Samples t test' or 'Mann-Whitney U test' in comparison of the groups, depending on the distribution of the data. Chi-square tests will be used to examine the relationships between categorical variables. 'Repeated Measure ANOVA' will be used in the evaluation of repeated measurements. Correlations between continuous variables will be analyzed by Pearson or Spearman correlation analysis, depending on the distribution of the data.

Outcome

Type Measure Description Time frame Safety issue
Primary Change from baseline in the cardiac enzyme levels Basal values of CK, CK-MB, Troponin-I will be studied in the preoperative period. In the postoperative period, CK, CK-MB, Troponin-I values will be studied 2 times; immediately at the end of the operation and in the 8th hour from the end of the operation. 3 times in 24 hours in the perioperative period
Primary Change from baseline in the hemodynamic parameters : Systolic and diastolic blood pressures (SAP and DAP) All patients will be monitored with routine anesthesia monitoring and bispectral index: SAP and DAP in mmHg will be checked and recorded in 5 minute intervals throughout the operation. SAP, DAP will be checked and recorded every 5 minutes throughout the operation time: from the beginning of anesthesia induction until the end of operation, in an estimated period of up to 6 hours.
Primary Change from baseline in the hemodynamic parameters : Heart rate (HR) All patients will be monitored with routine anesthesia monitoring and bispectral index: Heart rate (HR) in bpm , will be checked and recorded in 5 minute intervals throughout the operation. HR will be checked and recorded every 5 minutes throughout the operation time: from the beginning of anesthesia induction until the end of operation, in an estimated period of up to 6 hours.
Primary Change from baseline in the hemodynamic parameters : Peripheral oxygen saturation (sPO2) All patients will be monitored with routine anesthesia monitoring and bispectral index: Peripheral oxygen saturation (sPO2) in percent (%) will be checked and recorded in 5 minute intervals throughout the operation. sPO2 will be checked and recorded every 5 minutes throughout the operation time: from the beginning of anesthesia induction until the end of operation, in an estimated period of up to 6 hours.
Primary Change from baseline in the hemodynamic parameters : Bispectral index (BIS) All patients will be monitored with routine anesthesia monitoring and bispectral index: Bispectral index (BIS) will be checked and recorded in 5 minute intervals throughout the operation. BIS in percent (%) will be checked and recorded every 5 minutes throughout the operation time: from the beginning of anesthesia induction until the end of operation, in an estimated period of up to 6 hours.
