Goal-Directed Fluid Therapy in Patients Undergoing Lower Limb Surgeries

Not Applicable

Not yet recruiting

• Conditions: Anesthesia; ERAS; Hypovolemia; Surgical Shock; Fluid Overload

• Registration Number: NCT06133257
• Lead Sponsor: Zagazig University

Brief Summary

Controlling the amount of fluids given to patients in perioperative setting can significantly influence their outcomes.

Detailed Description

To overcome these problems and avoid the complications of over or underhydration, we use the Goal-directed fluid therapy(GDFT) guided by Inferior vena cava(IVC) collapsibility index approach in which dynamic parameters of volume responsiveness as a guide for fluid therapy. This will ensure that the fluids given were deficient from the circulation and improve the recovery of the patients according to enhanced recovery after surgery(ERAS) protocols.

Primary Outcome Measures

Name	Time	Method
Mean Arterial Blood Pressure	intraoperatively every 5 minutes	intraoperative mean arterial blood pressure measured in mmHg
Quality of Recovery-40 score(QoR-40)	24 hours postoperative	QoR-40 score ranges from 40 to 200, the higher the score the better the outcome
Heart Rate	intraoperatively every 5 minutes	intraoperative heart rate will be continuously monitored and recorded every 5 minutes
Post Anesthesia Care Unit(PACU) Stay	2 hours postoperatively	time spent in PACU after surgery measured in minutes

Secondary Outcome Measures

Name	Time	Method
Total fluid intake during operation	intraoperatively	Total fluid intake during operation
Number of patients that needed Ephedrine or Atropine	intraoperatively	Number of patients that needed Ephedrine or Atropine intraoperatively
Length of hospital stay	the patient will be followed up for 60 days from day of surgery	the number of days from day of surgery until patient's discharge from hospital
Peripheral perfusion index	Intraoperatively	Peripheral Perfusion Index (PPI) is defined as "the ratio of pulsatile blood flow to the non-pulsatile blood flow". It ranges from 0.02% to 20% and it is measured using specific types pulse oximetry and it reflects the perfusion status of the body.
