Description

Spinal and epidural anesthesia related perioperative nerve injuries have been recognized as a risk factor. Fortunately, neurologic complications that are severe or incapacitating are uncommon. Spinal cord ischemia, traumatic injury to the spinal cord or nerve roots during needle or catheter placement, infection, and choice of local anesthetic solution are all risk factors for neurologic deficit after neuraxial anesthesia. The neuraxial anesthetic is also frequently blamed for surgical trauma as well as postoperative neurologic injury caused by pressure from improper patient positioning or surgical dressings. Marinacci looked at 542 patients who had neurologic deficits after surgery that were thought to have been caused by spinal anesthesia. The spinal anesthetic was not the cause of the findings in any of the four cases. The remaining 538 patients' neurological problems appeared to be related to the spinal anesthetic, but this relationship was not definitive. Both an internal redistribution of body heat from the core to the perimeter and a net loss of heat to the environment cause core hypothermia following epidural anesthesia induction. However, it is still unknown how each mechanism contributes in proportion. An antecubital vein on the left arm was entered with an intravenous catheter. Each volunteer's skin and subcutaneous tissue over the L2-L3 or L3-L4 interspace were infiltrated with 2 milliliters of 1% lidocaine using a sterile technique. A loss of resistance to air and an 18-G Tuohy needle were used to locate the epidural space. An epidural catheter was progressed 2-3 cm into the epidural space.

For surgeries that take less than four hours or for patients at high risk for general anesthesia, single-dose spinal anesthesia is typically the preferred anesthetic. In surgeries for degenerative spinal disease in the lumbar region, spinal anesthesia is frequently used. When the anticipated duration of the surgery is suitable, there are known advantages to using spinal anesthesia for surgeries involving the spinal cord and the spinal column. The literature on spinal tumor surgeries performed under regional anesthesia is sparse. There are no reports of spinal anesthesiaonly surgical treatment for spinal tumors. Surgery for spinal tumors can be performed under spinal anesthesia for patients who have additional comorbidities and a high risk for general anesthesia. Surgery under spinal anesthesia is an option for patients who have a high ASA score, metastasis, poor general condition, or are elderly. However, lacks sufficient information regarding the outcomes of spinal tumor surgery performed under spinal anesthesia. In most cases, tumor surgery with lower extremity tumors required the use of spinal anesthesia. Patients with lumbar spinal tumors in ASA class 3 or 4 who are at high risk for general anesthesia can have spinal anesthesia administered. There is no difference in the applicability of general and spinal anesthesia unless the surgical procedure is completed within the estimated time for spinal anesthesia. When compared to patients who receive general anesthesia, there is a lower incidence of complications. A probe was used to measure the core temperature in the distal esophagus. The esophageal probe was unable to be swallowed by two volunteers: Mon-a- Therm thermocouples were used to measure their core temperatures from the tympanic membrane. Under the circumstances of this study, changes in the temperatures of the tympanic membrane and the distal esophageal membrane are nearly identical. Using a metabolic monitor that was calibrated, energy expenditure, which was derived from oxygen consumption and carbon dioxide production, was measured. Thermal flux transducers were used to measure heat flux and temperature from 15 skin-surface locations.
