About this study
Official title: Ketamine Versus Low Dose Thiopental for Rapid-sequence Induction of Anesthesia in Patients With Septic Shock
The aim of this work is to compare two protocols (ketamine-fentanyl-midazolam versus thiopental-fentanyl-midazolam) for induction of anesthesia in patients with septic shock aiming to find the most safe protocol with regards to hemodynamic status of patients.
Read the detailed description
Induction of anesthesia in hemodynamically compromised patients is a challenge for every anesthetist. Most of the intravenous induction agents have a negative effect on arterial blood pressure and cardiac output. Theoretically, the "ideal" emergency induction intravenous anesthetic should achieve rapid hypnosis and maintain the hemodynamic stability Ketamine has been reported as an induction anesthetic with a sympathomimetic activity. In patients with intact autonomic nervous system ketamine increases heart rate, cardiac output, and arterial blood pressure (ABP). Despite its sympathomimetic activity in hemodynamically stable patients, the hemodynamic response to ketamine in unstable cardiovascular conditions is not clear No studies to the best of our knowledge compared Ketamine and low dose thiopental in rapid sequence induction of anesthesia in hemodynamically unstable patients.
In this study, patients with severe sepsis or septic shock scheduled for surgery will be assigned to receive either ketamine or thiopental for induction of anesthesia. After induction of anesthesia, endotracheal tube will be inserted aided by succinyl choline. Invasive blood pressure will be monitored through a transducer connected to arterial catheter. Electrical velocimetry (cardiometry) device will be used for non-invasive monitoring of cardiac output and stroke volume.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
KetamineDrug
Also called Katalar
After fluid resuscitation, patients will receive :1 mg/Kg ketamine + 0.5 ug/Kg fentanyl + 0.05 mg/Kg midazolam for induction of anesthesia
ThiopentalDrug
Also called Intraval
After fluid resuscitation, patients will receive :2 mg/Kg Thiopental + 0.5 ug/Kg fentanyl + 0.05 mg/Kg midazolam for induction of anesthesia
| Study group | Role | What they receive |
|---|---|---|
| Ketamine group | Experimental | This group of patients will receive: 1 mg/Kg ketamine + 0.5 ug/Kg fentanyl + 0.05 mg/Kg midazolam for induction of anesthesia. Endotracheal tube will be inserted aided by 1 mg/Kg succinyl choline. Patients will undergo surgical procedure to eliminate the source of sepsis e.g. abdominal exploration. Invasive blood pressure monitor will be connected to the patient through an arterial catheter. Electrical velocimetry (cardiometry) device will be connected to the patient to measure cardiac output, stroke volume, and systemic vascular resistance. Receives: Drug: Ketamine |

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Ketamine and Thiopental in people with Septic Shock, run by Cairo University at 1 site in Egypt.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 10 Jul 2018. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Mean arterial pressure (time frame: 30 minutes after induction of anesthesia). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Jul 2018.
