Impact of Temperature on the Quality of Local Anesthetic Effect during Subarachnoid Block

Abstract

In contrast to general anesthesia, which affects the entire body, spinal anesthesia specifically targets a limited area, leading to a temporary loss of sensory and motor function. The duration of the effect varies on many factors depending on the specific anesthetic agent used, level of injections given and, baricity, dose, temperature and, many more factors. The temperature of the administered bupivacaine solution has been recognized as a potential modulator of its onset of action, influencing factors such as speed, depth, and duration of anesthesia. The temperature of the medication can influence the speed at which the local anesthetic takes effect. Warmer solutions may have a faster onset of action compared to colder ones. The duration of anesthesia may also be affected, with warmer solutions potentially providing a more prolonged effect. The temperature of the injected medication can influence the patient's comfort during the administration of spinal anesthesia. The present analysis indicates that there is a definite relationship between the temperature of the injected local anesthetic and the quality of the block achieved.
