Nausea and vomiting was documented either as absent or present. [sciforschenonline.org]
Patwardhan, “At present there is no pharmaceutical treatment for this very important clinical need that is currently managed only with physical methods that are often insufficient and problematic to both patients and clinical staff”. [techlaunch.arizona.edu]
Entire Body System
- Hypothermia
This response was absent in patients undergoing cardiac surgical procedures associated with the combination of cardiopulmonary bypass, narcotic anesthesia, neuromuscular blockade, and hypothermia. [ncbi.nlm.nih.gov]

Nonetheless, the incidence of hypothermia after surgery is still high. [signavitae.com]
- Falling
While active warming, usually with forced air, has become the standard of care, the researchers add, a patient's core temperature falls sharply in the first hour of anesthesia, due to core-to-peripheral body heat distribution. [scientificamerican.com]
Upon anesthetic induction, body temperature initially falls due to the internal distribution of heat from core to peripheral compartments and then temperatures continue to fall (0.5 to 1 degrees Celsius per hour (35,36) until a difference is established [ispub.com]
When core temperature falls early in a procedure, despite active warming, clinicians doubt the effectiveness of the intervention. [apsf.org]
Due to the affected thrombocyte function, high tendency of bleeding exists, however real thrombocyte number does not fall down until a serious hypothermia (hypothermic thrombocytopenia). [article.sciencepublishinggroup.com]
Broadly speaking, these fall into one of two categories: monitors of cerebral substrate delivery [jugular bulb oximetry, transcranial Doppler sonography, and near infrared spectroscopy (NIRS)] and monitors of cerebral function [quantitative electroencephalography [academic.oup.com]

Poor outcome was defined as severe disability, vegetative state, and death using the Glasgow Outcome Scale [ 63 ]. [hoajonline.com]
- Plethora
Temperature monitoring is measured from a plethora of sites. Sites commonly used for measurement of temperature are: skin, tympanic membrane, bladder, esophagus, nasopharynx, pulmonary artery, and jugular bulb. [hoajonline.com]
Cardiovascular
- Hypertension
Less hypotension with no significant hypertension was found when 0.15 mg/kg ephedrine was combined with 2.5 mg/kg of propofol, and 3 μg/kg of remifentanil [ 7 ]. [degruyter.com]
Conduction abnormalities, hypertension, and bradyarrhythmias are much more prevalent in the elderly (29). [ispub.com]
Extubation 10 mins faster with forced air warming [Mahoney] Increased Cardiac Morbidity NOT due to shivering, possibly arrhythmias, hypertensive response to stress of cold [Frank SM et al. JAMA 277: 1127, 1997]. [openanesthesia.org]
Exclusion criteria included ASA physical status score of III or greater, thyroid disease, Raynaud’s syndrome, autonomic neuropathy, hypertensive disease of pregnancy, preeclampsia, BMI greater than 35, and non-English speaking. [sciforschenonline.org]
Severe shivering may also result in tachycardia, hypertension, and myocardial ischemia, which could lead to cardiac arrest ( Sessler, 2008 ). [aneskey.com]
- Hypotension
If systolic blood pressure remained below 90 mmHg, the patient would be recorded as having hypotension. [degruyter.com]
First, there was not a control group due to the necessity to treat hypotension following spinal anesthesia. [sciforschenonline.org]
With more severe hypothermia there is decreased catecholamine responsiveness, resulting in bradycardia and hypotension. Arrhythmias can occur due to myocardial ischemia. [blog.vetbloom.com]
In liver patients, bromocriptine 2.5-10 mg PO tid is an alternative but hypotension is a potential side effect. Both treatments should be continued for 10 days, and DVT prophylaxis should be added. [openanesthesia.org]
Attention should also be paid to avoiding other factors, such as hypotension and hypoxaemia, that exacerbate brain injury. The pattern of brain injury after DHCA varies between adults and neonates. [academic.oup.com]
- Tachycardia
The prevalence of cardiac incidents, myocardial ischemia and tachycardia is increased. Development of coagulopathy with greater blood loss even for 0.5°C occurs as a result of platelet and clotting factor dysfunction. [signavitae.com]
Severe shivering may also result in tachycardia, hypertension, and myocardial ischemia, which could lead to cardiac arrest ( Sessler, 2008 ). [aneskey.com]
In a prospective study, Frank et al., demonstrated that patients who were allowed to become hypothermic did not differ from patients in which normothermia was maintained in the incidence of intraoperative ventricular tachycardia and myocardial ischemia [hoajonline.com]
Neurologic
- Amnesia
In 33°C, high cerebral functions and retroactive amnesia are seen. Human loses consciousness between 30°C to 28°C [ 11 ]. 2.8. [article.sciencepublishinggroup.com]
Treatment
Therefore, all procedures that last longer than 30 minutes should include temperature monitoring. (6) What kind of warming treatments are mostly used? There are two main treatment options for managing hypothermia, the passive or the active approach. [signavitae.com]
Now that the company has the license for the technology, they plan to in-license a TRPV-1 antagonist to enter into clinical trials to test it as a treatment for anesthesia-induced hypothermia. [techlaunch.arizona.edu]
Treatment The main difference between the treatment of primary and secondary hypothermia is that the best treatment for secondary hypothermia is prevention. [blog.vetbloom.com]
Both treatments should be continued for 10 days, and DVT prophylaxis should be added. [openanesthesia.org]
All problems (adverse events) related to a medicine or medical device used for treatment or in a procedure should be reported to the Medicines and Healthcare products Regulatory Agency using the Yellow Card Scheme. [nice.org.uk]
Prognosis
With severe hypothermia ( Rewarming complications can affect the prognosis of hypothermic patients. [blog.vetbloom.com]
Etiology
Redistribution of body heat from the core to the periphery is the most common etiology of hypothermia in the first hour after induction of anesthesia and this reduction in temperature is commonly 1-1.5 °Celsius. [openanesthesia.org]
There is a wide range of etiologies for fevers that can be categorized into syndromic, infectious or noninfectious [ 28, 33 - 35 ]. [hoajonline.com]
This chapter will review both the physiology of temperature regulation and the etiology of unplanned perioperative hypothermia, the relationship between surgical complications and hypothermia, as well as approaches to prevent and treat unplanned hypothermia [aneskey.com]

Although isothermic irrigation fluid was suggested to prevent perioperative hypothermia, it can be difficult to warm a large volume of irrigation fluid. [clinicaltrials.gov]
Prevention of perianesthetic hypothermia requires close patient monitoring with rectal or esophageal thermometers. Indwelling probes allow for continuous temperature monitoring. Therapies to prevent and treat hypothermia are very similar. [blog.vetbloom.com]
Forced air warming devices and intravenous fluid warming system at room temperature successfully prevent and treat hypothermia. (5, 15) However, the intravenous fluid warming system just prevents hypothermia due to the fact that four litres of saline [signavitae.com]
Preventing hypothermia soon became a Centers for Medicare & Medicaid Services quality indicator linked to hospital reimbursement. No longer were trips to the OR allowed to be so chilling. [nurse.com]
