Spinal block causes paralysis of preganglionic sympathetic fibres, while ketamine induces activation of the sympathetic nervous system. Hypotension is a frequent complication during spinal anaesthesia and is associated with an increased risk of postoperative mortality. The aim of our study was to compare circulatory changes in patients who received either fentanyl or ketamine during spinal anaesthesia. Thirty patients (ASA I‐III) scheduled to undergo spinal anaesthesia for osteosynthesis of hip… Expand

Evaluation of the Efficacy of Intravenous Ketamine on Prevention of Hypotension During Spinal Anaesthesia in Patients with benign Prostatic Hyperplasia
TLDR
Ketamine .5 mg/kg b.w. given intravenously just after spinal anaesthesia resulted in greater hemodynamic stability in elderly patients undergoing transurethral resection of prostate compared with control group. Expand
THE EFFECT OF INTRAVENOUS KETAMINE ON PREVENTION OF HYPOTENSION DURING SPINAL ANESTHESIA IN PATIENTS WITH BENIGN PROSTATIC HYPERPLASIA
Objective: Hypotension is a common complication during spinal anesthesia. The elderly are at an increased risk of developing complications from hypotension due to reduced physiological reserves.… Expand
Effect of low-dose ketamine on redistribution hypothermia during spinal anesthesia sedated by propofol.
TLDR
Low-dose ketamine administration may confer thermoprotection during spinal anesthesia sedated by propofol infusion, and the core temperature linearly decreased over time. Expand
Circulatory Responses to Propofol-Ketamine Combination Compared to Propofol Alone for Sedation During Spinal Anaesthesia
TLDR
The propofol-ketamine combination confers hemodynamic stability during spinal anaesthesia as compared to Propofol alone, and sedation scores revealed no significant difference at the predetermined time intervals between the two groups. Expand
A Comparison of Propofol with a Propofol-Ketamine Combination for Sedation During Spinal Anesthesia
TLDR
Although the described additive effect of propofol and ketamine was not confirmed, the combination conferred hemodynamic stability during spinal anesthesia. Expand
Impact of Sub-Anesthetic Dose of Ketamine on Post Spinal Hypotension in Cesarean Delivery
TLDR
This double-blinded randomized controlled study was conducted on 80 participating parturients who were ASA І, П term pregnant, and ketamine group received a sub-anesthetic dose of ketamine and control group received the same volume of normal saline IV bolus. Expand

The role of vasopressors in the management of hypotension induced by spinal and epidural anaesthesia

TLDR
In this review, the role of vasopressor agents is discussed and possible future management strategies are commented upon. Expand
Comparison of the cardiopulmonary effects of anesthesia maintained by continuous infusion of ketamine and propofol with anesthesia maintained by inhalation of sevoflurane in goats undergoing magnetic resonance imaging.
TLDR
Results suggest that ketamine-propofol total IV anesthesia in goats breathing 100% oxygen is practical and safe for performance of magnetic resonance imaging procedures. Expand
Hemodynamic effects of epidural ketamine in isoflurane-anesthetized dogs.
TLDR
The results suggest that if epidural ketamine is used for analgesia in dogs, it will induce minimal changes in cardiovascular function and no significant differences were detected from baseline values at any time after ketamine injection. Expand

Effect of fluid preloading on cardiovascular variables after spinal anaesthesia with glucose-free 0.75% bupivacaine.
TLDR
Glucose-free 0.75% bupivacaine did not give a reliable extent of anaesthesia for lower abdominal surgery and the group not given a fluid preload had significantly lower arterial pressures when anaesthesia extended above the T5 dermatome. Expand
Prophylactic ephedrine during spinal anaesthesia: double-blind study in patients in ASA groups I-III.
TLDR
It is concluded that prophylactic ephedrine is desirable for spinal anaesthesia, especially in ASA III patients, after a large number of patients developed a maximal decrease in mean arterial pressure exceeding 20%. Expand
[Risk and hemodynamic instability in spinal anesthesia].
TLDR
It is concluded that the risk of fall in blood pressure during spinal anaesthesia may be predicted by the Boston Cardiac Risk Index and that patients who develop haemodynamic instability during spinal Anaesthesia have an increased risk of developing complications. Expand
Epidural and subarachnoid anesthesia. Cardiovascular and respiratory effects.
TLDR
Unmedicated patients blocked by high subarachnoid anesthesia are able to hyperventilate and maintain normal blood gas tensions, and high epidural block without epinephrine produces changes similar to, but not as profound as, subaracheal anesthesia. Expand

By reviewing several studies of preoperative risk factors, the author attempts to find which factors imply significant risk of mortality in surgical patients with cardiac disease. Expand
