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.

Condition or disease Intervention/treatment Phase
Hemodynamic Instability Fluid Therapy Anesthesia; Adverse Effect Other: gelofusine Not Applicable

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.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 80 participants
Allocation: Randomized
Intervention Model: Single Group Assignment
Intervention Model Description: Non-blinded randomization. Standardized method comparison.
Masking: None (Open Label)
Primary Purpose: Other
Official Title: Hemodynamic Stability During an Induction of Anaesthesia: A Randomized, Non-blinded Study
Actual Study Start Date : November 20, 2017
Estimated Primary Completion Date : December 15, 2018
Estimated Study Completion Date : May 15, 2019

Arm Intervention/treatment
Experimental: Preoperative fluids
40 individuals receiving preoperative colloid fluid bolus at 6 ml/kg LBW, (Gelofusine™, Fresenius Kabi AB, Sweden) before anesthesia induction by TCI (n = 20) or RSI (n =20).
Other: gelofusine
Preoperative colloid fluid bolus 6ml/kg ideal body weight
Other Name: colloid fluid

No Intervention: No preoperative fluids
40 individuals anesthetized by TCI (n = 20) or RSI (n =20) without preoperative fluids.

Primary Outcome Measures :
  1. Incidence of blood pressure drops [ Time Frame: 20 minutes post anesthesia induction ]
    blood pressure drop below mean arterial pressure at 65 mmHg during anesthesia induction

  2. Effect of preoperative fluid bolus [ Time Frame: 20 minutes post anesthesia induction ]
    Does preoperative fluid bolus decrease incidence of blood pressure drops
