Brief summary
The study aim is to investigate if preoperative volume bolus based on lean body weight could preserve mean arterial pressure during target controlled infusion of anaesthesia (TCI) or rapid sequence induction of anaesthesia (RSI) in non-cardiac, non-morbidly obese surgery.
Detailed description
40 individuals are enrolled to TCI and RSI groups respectively. The randomization process for preoperative fluid bolus prior to induction of anaesthesia is conducted in respective group at the day of surgery. Preoperative colloid fluid therapy (6 ml/kg LBW, Gelofusine™, Fresenius Kabi Ab, Sweden) is infused rapidly before non-invasive baseline blood pressure (NIBP) measurements in twenty individuals in each group. No other intravenous fluids before induction of anaesthesia. NIBPs, pulse frequency, peripheral saturation (SpO2) are registered and collected 20 minutes post induction.
Interventions

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Incidence of blood pressure drops | 20 minutes post anesthesia induction | blood pressure drop below mean arterial pressure at 65 mmHg during anesthesia induction |
| Effect of preoperative fluid bolus | 20 minutes post anesthesia induction | Does preoperative fluid bolus decrease incidence of blood pressure drops |
