If the midline approach is used, palpate the desired interspace and inject local anesthetic into the skin and subcutaneous tissue. 2015;29:32673272. Average CO and MAP changes plus or minus standard deviation during onset of spinal anesthesia in elderly patients. 173. However, CSF volume varies considerably, and decreased CSF volume can result from obesity, pregnancy, or any other cause of increased abdominal pressure. Following systemic absorption, local anesthetics can produce central nervous system stimulation, depression or both. Although many arguments are made against general anesthesia in the pregnant woman due to increased risk of aspiration and difficult intubation, the anesthesiologist must be prepared to induce general anesthesia in the face of a failed or total spinal anesthetic. Resuscitation 132 : 127-132, 2018, 2) Benson MD, et al : Maternal collapse : Challenging the four-minute rule. Categories. 2018;18:64. In total, the first stage of labor may take some 12 to 19 hours. However, there are very few studies directly comparing the efficacy of a risk-based restrictive antiemetic prophylaxis approach to a more liberal multimodal antiemetic prophylaxis approach. Sedative and analgesic medications all impair thermoregulatory control to some extent.109,127,137,161 Such inhibition may be severe when combined with the intrinsic impairment produced by regional anesthesia and other factors, including advanced age or pre-existing illness (fig.

Local anesthetics travel across the dura in both directions. It thus seems unlikely that an imbalance between heat production and loss is the explanation for hyperthermia during labor analgesia. 1998;13:589595.

The first mechanism is by diffusion from the CSF to the pia mater and into the spinal cord, which is a slow process. However, a systematic review reported that colloids were more effective in reducing the risk of PONV in surgeries lasting >3 hours, but not in those lasting <3 hours (evidence A1).74 Dextrose solutions infused intraoperatively or postoperatively were not found to be effective in reducing the risk of PONV (evidence A1).300, Administration of a preoperative carbohydrate drink is included in many of the ERPs.

Caution should be exercised when using the 300 mg dose [see OVERDOSE]. They concluded that objections to spinal anesthesia were undeserved. Postulated mechanisms for this include an inability to shiver due to more pronounced motor block with spinal anesthesia and a decreased shivering threshold with more dermatomes (and thus thermoregulatory afferents) blocked during spinal anesthesia. Lieberman E, Lang JM, Frigoletto F, Richardson DK, Ringer SA, Cohen A. Epidural analgesia, intrapartum fever, and neonatal sepsis evaluation. In a clinical trial of 1147 patients, the combination of amisulpride with ondansetron or dexamethasone was more effective than ondansetron or dexamethasone alone in reducing PONV and rescue antiemetic requirement (evidence A3).261.

However, the haloperidol cohort demonstrated significantly more sedation.202, There is also emerging evidence for the use of NK1 receptor antagonist in treating established PONV. An SRMA, while statistically heterogeneous, found reduced rates of PONV as a secondary outcome in children receiving intranasal dexmedetomidine for separation anxiety when compared to intranasal or oral midazolam (evidence A1).111 In a randomized double-blinded study, the oral clonidine group had significantly less episodes of PONV and need for rescue antiemetics compared to the placebo group.108 Further evidence is needed in children, but 2 agonists warrant consideration in multimodal regimens aimed at reducing PONV risk in children. It was hypothesized that due to beneficial modulation of the stress response, regional anesthesia would besafer than general anesthesia.

Interestingly, core hypothermia during regional anesthesia may not trigger a perception of cold.43,162 The reason is that thermal perception (behavioral regulation) is largely determined by skin rather than core temperature.78 During regional anesthesia, core hypothermia is accompanied by a real increase in skin temperature. Fox RH, Solman AJ. Br J Anaesth. Prophylactic IV acetaminophen as part of a multimodal analgesic regimen reduces nausea, only if given before the onset of pain (evidence A1).76 After a gastrectomy, IV acetaminophen, in addition to continuous epidural analgesia, showed decreased opioid use and a significantly reduced incidence of PONV.77 While oral acetaminophen has also been shown to reduce opioid requirement78 and is considerably less costly, its effect on PONV is not well-studied. Spinal anesthesia itself may cause IONV or postoperative nausea and vomiting (PONV) via a variety of mechanisms, including hypotension, intrathecal additives, inadequate nerve block, or high nerve block. Adequate preparation for the spinal reduces the amount of time needed to perform the nerve block and assists with making the patient comfortable. BMC Musculoskelet Disord.

These are complications a patient would consider severe. Promethazine is also effective for the treatment of established PONV, with doses as low as 6.25 mg being as effective as higher doses and associated with less sedation277,278 (evidence A2). In contrast, general anesthetics have relatively little effect on the gain and maximum intensity of thermoregulatory responses. 104.
