Influence of total intravenous anesthesia, entropy and laparoscopy on oxidative stress.

Background And Objectives: Recent studies have correlated postoperative mortality with anesthetic mortality, especially with the depth of anesthesia and systolic blood pressure (SBP). The aim of this study is to evaluate the effects of the depth of total intravenous anesthesia (TIVA) using remifentanil and propofol, performed with monitoring of response entropy (RE) on blood concentrations of oxidative stress markers (TBARS and glutathione) during laparoscopic operations.

Method: Twenty adult patients, ASA I, BMI 20-26 kg.

Total intravenous anesthesia with target-controlled infusion of remifentanil and propofol for ablation of atrial fibrillation.

Background And Objectives: Although ablation of atrial fibrillation (AF) is common in other centers, among us it is a new procedure. The choice of anesthesia, monitors, and anesthesiologic care for this procedure performed outside the surgical center has not been described. The objective of this report was to describe an anesthesia technique for ablation of AF.

Target-controlled total intravenous anesthesia associated with femoral nerve block for arthroscopic knee meniscectomy.

Background And Objectives: The increased popularity of minimally invasive surgical techniques reduced recovery time of procedures that were usually associated with prolonged hospitalization. This study reports the technique of total intravenous anesthesia with propofol and remifentanil associated with femoral nerve block using the inguinal perivascular approach.

Methods: Ninety patients undergoing knee arthroscopy for meniscectomy were included in this study.

Total intravenous anesthesia as a target-controlled infusion. An evolutive analysis.

Background And Objectives: Total intravenous anesthesia (TIVA) has seen several developments since it was first used. Since the synthesis of the first intravenous anesthetics, with the introduction of barbiturates (1921) and thiopental (1934), TIVA has evolved until the development of TIVA with target-controlled infusion pumps (TCI). The first pharmacokinetic model for the use of TCI was described by Schwilden in 1981.

[Remifentanil: does the infusion regimen make a difference in the prevention of hemodynamic responses to tracheal intubation?].

Background And Objectives: High doses of opioids decrease the hemodynamic response to tracheal intubation. However, the slow recovery profile of traditional opioids may limit the use of high doses. Remifentanil has a fast time of onset and is short acting, which differentiates it from the other drugs in this class.

[Current attitude of anesthesiologists and anesthesiology residents regarding total intravenous anesthesia.].

Background And Objectives: In the past, time, cost, information, training, and the evaluation of the plane of anesthesia limited the acceptance of total intravenous anesthesia (TIVA). The objective of this study was to determine the attitude of anesthesiologists and other anesthesiology residents regarding total intravenous anesthesia.

Methods: A questionnaire was sent to 150 anesthesiologists and 102 residents.
