Oxidative Stress Clinical Trial
Official title:
Impact of Mode of Anesthesia on Ischemia Modified Albumin (Abiomarker of Oxidative Stress) and Outcome in Patients With Traumatic Brain Injury Undergoing Emergency Craniotomy
In the current study the investigators intend to evaluate the mode of anesthesia on ischemia modified albumin and outcome in patients with traumatic brain injury undergoing emergency craniotomy
After obtaining Institutional Ethical Committee approval and written informed consent from
legally acceptable representative relatives, patients with traumatic brain injury, aged from
18- 60 years old, ASA from (I-III), GCS more than 8 undergoing emergency craniotomy surgery
will be selected for this prospective randomized Study.
The anesthesia will be induced with 2mcg/kg fentanyl and 2 mg/kg propofol. Muscle relaxation
will be achieved with 0.5 mg/kg atracurium.
Anesthesia will be maintained with:
- Group I, isoflurane (mac<1) mixed with oxygen 40% and fentanyl 1mcg/kg hourly.
- Group PD, propofol infusion(100-150mcg/kg/min) and dexmedetomedine 0.3mcg/kg /h.
Parameters will be assessed Preoperative period
- Ischemia modified albumin level from venous sample.
- Basal Systolic blood pressure, diastolic blood pressure. Mean arterial blood pressure,
oxygen saturation, heart rate.
- GCS. Intraoperative period
- Systolic blood pressure, diastolic blood pressure. Mean arterial blood pressure, oxygen
saturation, heart rate after intubation, 5,15,30,60,90min and after extubation.
- Need for resuscitation with vasoactive drugs.
- Brain relaxation score at dural opening and closure.
- ICP
- Intraoperative blood loss.
- Amount of fluid and blood transfusion. Postoperative period
- Ischemia modified albumin immediately postoperatively, after 6h and after 24 hours.
- Type of surgery.
- Duration of surgery.
- Extubation time.
- Recovery scores (Ramsay sedation score and modified Alderte score).
- GCS immediately postoperatively, after 6h, after 24h and after 48 hours.
- Total analgesic requirement during the first 24 hours.
- Need for ICU admission.
- Length of ICU stay.
- Complications.
- 28 day mortality.
