“…To reconcile our previous [1] with our present findings, we postulate that either pregnancy enhances the contribution of spinal thermoregulatory input, or local anaesthetic facilitates shivering.…”

“…Previous work has shown that shivering during extradural anaesthesia for Caesarean delivery is more common after administration of cold than after warm bupivacaine [1], suggesting that the extradural space is sensitive to temperature changes. We report here the effects of injecting warm and cold saline into the lumbar extradural space of non-pregnant volunteers.…”

We tested the hypothesis that cooling the extradural space may provoke shivering, by giving three 80-ml extradural injections of warm (39.8 +/- 1.2 degrees C) or cold (17 +/- 2.2 degrees C) saline to four healthy volunteers, whilst recording central temperature and electromyographic activity from four muscles. The first injection (always cold) did not induce shivering in any of the subjects. The second and third injections, randomly cold or warm, were given after induction of shivering with cold blankets, but had no detectable effects on the intensity of shivering. This suggests that shivering in extradural anaesthesia does not result solely from cooling of the extradural space.

“…Shivering during epidural anesthesia for cesarean section was more common after administration of cold rather than warm bupivacaine [119] , However, when testing the hypotheses that cooling the epidural space may produce shivering, it was conclud ed that the contribution of the anesthetic temperature to shivering is likely to be minimal in a clinical setting [ 120] , Inadequate epidural analgesia is encountered when the block is incomplete or unilateral. The most frequent cause of an incomplete block is a catheter advanced too far into the anterior epidural space or out an intervertebral fora men [1].…”

Lumbar epidural analgesia has become the preferred method of pain relief for labor and delivery. Proper administration of epidural analgesia offers many advantages for both mother and fetus. With the availability of various local anesthetics, opioids, and infusion techniques, the analgesia can be tailored to the specific needs of the mother, fetus, and labor. Its effect on the progress of labor remains a controversial topic subject to ongoing investigation.

“…Previous studies have suggested the existence of thermosensory mechanisms in the human spinal canal that are responsible for reduction of incidence of shivering after injection of warm epidural or spinal anaesthetic solutions. However, influence of temperature of the drug in spinal anaesthesia on shivering is still controversial [10][11][12]. Therefore, we conducted this study with an objective to analyse the impact of three different temperatures of the hyperbaric bupivacaine on the incidence of post-spinal shivering in cesarean section.…”
