BACKGROUND AND AIMS Oncosurgeries may incur massive blood loss demanding frequent blood sampling to assess blood loss and the need for intraoperative blood transfusions. Accuracy of non-invasive spectrophotometric haemoglobin (hereafter to be referred as SpHb) monitoring has been studied in various perioperative settings. The intraoperative use of Radical-7®, Masimo Corp., (Radical-7®) for SpHb...

OBJECTIVES/HYPOTHESIS Demonstrate whether intraoperative nerve monitoring is an effective tool in staging bilateral thyroid and neck surgeries in cases of intraoperative injury to the recurrent laryngeal nerve on the side of initial dissection. We hypothesized that IONM provides reliable and appropriate feedback on the functional status of the RLN on side of initial dissection during total thyr...

Intraoperative parathyroid hormone monitoring (IOPTH) has changed the surgical approach to primary hyperparathyroidism (PHPT). The traditional approach for the treatment of PHPT is a bilateral neck exploration (BNE), which entails the identification of all parathyroid glands and resection of the abnormal glands. However, with the advent of improved surgical adjuncts, including preoperative ultr...

Selective Dorsal Rhizotomy (SDR) is a neurosurgical procedure currently used as a surgical treatment of children with spasticity in their legs. In SDR, the dorsal roots from L2 to S1 or S2 is partially sectioned. The primary goal of SDR is to reduce spasticity and improve the range of movement with preservation of muscle strength. The dorsal roots involved in spasticity are identified on the ba...

Intraoperative neurophysiologic monitoring was performed in a patient by somatosensory evoked potential, motor evoked potential and free-running electromyography with intraoperative stimulation. It was verified that after decompression, there was an increase in the amplitude of motor evoked potential responses, showing an immediate improvement of the treated levels. Intraoperative neurophysiolo...

Intraoperative management of patient body temperature is a standard of care for practicing anesthesiologists. Merely complying with the Surgical Care Improvement Project (SCIP) measurement is inadequate for optimizing perioperative outcomes. Clinicians should have a sound understanding of available temperature monitoring sites, deleterious effects of hypothermia, and indications for therapeutic...

Intraoperative fluid management is pivotal to the outcome and success of surgery, especially in high-risk procedures. Empirical formula and invasive static monitoring have been traditionally used to guide intraoperative fluid management and assess volume status. With the awareness of the potential complications of invasive procedures and the poor reliability of these methods as indicators of vo...

Many of injured children will require surgical treatment with involvement of the anesthesiologist. The anesthesia providers may have to take care of pediatric patients on following occasions: 1- Initial stabilization in the emergency department 2- Providing sedation and monitoring for imaging 3- Preoperative management of emergent surgical procedures such as laparotomy or craniotomy 4- Manageme...

Background and Importance: The development of C5 root palsy is a well-known potential complication of cervical spine surgeries for the correction of cervical spondylotic myelopathy. It typically occurs unilaterally but on extremely rare occasions it might occur as a bilateral anomaly. The value of intraoperative neurophysiologic monitoring in detection of iatrogenic acute versus delayed onset C...

Total hip arthroplasty (THA) for patients with Crowe type IV developmental dysplasia of the hip is technically challenging. This group of patients has a higher incidence of nerve injury during THA. Although neurophysiologic intraoperative monitoring has been developed to provide nerve monitoring, it is not always available. The wake-up test has been used for intraoperative spinal cord monitorin...
