Metallic foreign objects can cause various thermal injuries in patients undergoing magnetic resonance imaging (MRI). We present a case of a 33-year-old woman with numerous metallic microbeads on her head used for attaching hair extensions, who required MRI of her cervical spine under anesthesia. Due to the nature of how these microbeads were attached, as well as the quantity and configuration, these objects were determined to be a significant risk, especially for a patient requiring anesthesia for their scan.

Background Children undergoing cranial or craniospinal radiotherapy may require over 30 treatments within a six-week period. Facilitating these many treatments with the patient under anesthesia presents a significant challenge, and the most preferred anesthetic methods remain unknown. The primary goal of this study was to determine the most preferred anesthetic methods and agents for children undergoing daily cranial or craniospinal radiotherapy.

Background: The impact of patient ethnicity on healthcare delivery is well documented. In this study of children who had undergone open abdominal or pelvic surgery for tumor resection, we sought to compare the use of epidural analgesia or intraoperative blood transfusions between Caucasian and non-Caucasian children.

Methods: A retrospective study of 139 children was performed.

Objective: Recent evidence suggests the α2-adrenoreceptor agonist dexmedetomidine may promote metastasis of cancer cells. In this study we sought to evaluate the impact of dexmedetomidine administration on the survival of children and adolescents with cancer.

Design: Retrospective chart review.

Background: In adults, preoperative opioid use and higher perioperative opioid consumption have been associated with higher odds of persistent opioid use after surgery. There are limited data on the prevalence and factors associated with persistent opioid use after major oncologic surgery in children.

Aims: In this study, we sought to determine the prevalence and factors associated with the development of persistent opioid use in a group of children and adolescents who had undergone cytoreductive surgery with hyperthermic intraperitoneal chemotherapy.

Background: Acute kidney injury (AKI) is a postoperative complication associated with significant morbidity and mortality. The incidence and risks factors for AKI after cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) have not been fully studied. The purpose of this study was to identify perioperative risk factors predictive of AKI after CRS-HIPEC.

Background: Several studies in adult patients have suggested an unfavorable association between opioid consumption and cancer progression.

Aims: This study investigated the impact of opioid consumption on the survival of children and adolescents undergoing cytoreductive surgery with hyperthermic intraperitoneal chemotherapy.

Methods: A retrospective study of patients <19 years who had undergone cytoreductive surgery with hyperthermic intraperitoneal chemotherapy was performed.

Neurofibromatosis type 1 is an autosomal-dominant disorder with the tendency toward the formation of tumors. Plexiform neurofibromas are the most common type of tumors seen in neurofibromatosis type 1. Approximately 50% occur in the head and neck region with a 5% incidence of airway involvement.

Purpose: The aim of this study was to assess the impact of total intravenous anesthesia (TIVA) on the perioperative inflammatory profile and clinical outcomes of patients undergoing cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS-HIPEC).

Methods: A retrospective review of patients undergoing CRS-HIPEC was performed. Patients receiving a combination of preoperative tramadol extended release (ER), celecoxib, and pregabalin, along with combined intraoperative infusions of propofol, dexmedetomidine, lidocaine, and ketamine were classified as receiving a TIVA regimen (TIVA group).

Background And Purpose: Physicians responsible for anesthesia and/or sedation (A/S) at emerging proton radiation therapy centers (PTCs) seek information about practices at established centers. We conducted a survey of A/S practices at established PTCs to provide this information for physicians at new PTCs.

Methods And Materials: A web-based survey was sent to physicians responsible for A/S at 37 established PTCs.

Mitochondrial neurogastrointestinal encephalomyopathy (MNGIE) is an autosomal recessive disorder associated with deficiency of thymidine phosphorylase (TP). Associated manifestations include visual and hearing impairments, peripheral neuropathies, leukoencephalopathy, and malnutrition from concomitant gastrointestinal dysmotility and pseudoobstruction. Given the altered metabolic state in these patients, specific consideration of medication selection is advised.
