Malignant hyperthermia (MH), characterized by severe myoclonus, pyrexia, tachycardia, hypertension, elevated muscle enzymes, and hypercapnia, often occurs in patients with congenital deformities or genetic disorders. Although the reported incidence rate is as low as 1:5000 to 1:100,000, patients with MH exhibit rapid aggravation and an elevated mortality rate. Thus, MH is associated with substantial perioperative risk. Successful treatment of patients with MH largely depends on early diagnosis and timely effective treatment. This clinical report provides a detailed description of a patient with newly diagnosed MH who developed a rapid rise in body temperature, end-tidal carbon dioxide, and heart rate during maxillary osteotomy. After successful rescue, the patient recovered smoothly during the postoperative period, indicating the importance of intraoperative monitoring, early diagnosis, effective treatment, and postoperative monitoring. This case is expected to serve as a reference for future interventions and healthcare practices in managing other patients with MH.

A 32-year-old multigravida woman, with known familial hypokalaemic periodic paralysis, underwent spinal anaesthesia for an elective lower segment caesarean section. There are several case reports in the literature discussing the optimal anaesthetic technique. In the past there has not been an emphasis on aggressive and early potassium replacement. A target level to commence replacement of potassium at 4.0 mmol/L or less is proposed. Careful preoperative preparation, frequent perioperative monitoring and early potassium replacement resulted in no perioperative episodes of weakness in this case, in contrast with other case reports where potassium was either not monitored or not replaced early enough, resulting in postoperative attacks. Another factor to consider in hypokalaemic periodic paralysis is the avoidance of triggers, including certain medications. Misoprostol was used in this instance to avoid potential electrolyte derangements from other uterotonics.

Perioperative crisis events refer to unexpected seriously life-threatening when the patient is during or after surgery, and require rapid identification, evaluation, and management by clinical teams to minimize harm. The pediatric anesthesia management during perioperative period is special and challenging for anesthesiologists, requiring professional technical and non-technical skills. The article mainly elaborates on the incidence and risk factors of pediatric anesthesia crisis events during perioperative period and introduces the concept of anesthesia crisis resource management and strategies. The anesthesiologist team needs to adopt a crisis resource management strategy, taking a typical crisis event of malignant hyperthermia as an example, including identification of crisis signs immediately, termination of trigger drugs rapidly, intravenous injection of the special drug dantrolene, physical cooling, and symptomatic support treatment, seeking assistance from other teams actively, recording and feeding back. This study aims to improve the cognitive decision-making ability and teamwork ability of anesthesiologists and their teams, effectively preventing and responding to potential crisis events effectively, and ensuring the safety of pediatric patients during perioperative period.

Anesthesiologists have been at the forefront of initiatives addressing perioperative patient safety. As anesthesia has no direct therapeutic benefit, its risk must be minimized. At times the surgery is simple but the patient\'s condition complicates anesthetic management, increasing the risk for complications. This report describes the anesthetic management of an adult patient diagnosed with inclusion body myositis (IBM), a rare inflammatory degenerative myopathy, who initially presented with decreased motor function in both lower and upper extremities causing him to be bedbound for two years. Due to the progression of his disease, he eventually developed dysphagia, hence he was scheduled for esophagoscopy, cricopharyngeal Botox injection, and percutaneous endoscopic gastrostomy. As patients with IBM are at risk for exaggerated sensitivity to neuromuscular blockers and respiratory compromise, anesthesia was at the helm of a multidisciplinary team approach. The perioperative management centered on preoperative optimization, prevention of aspiration, avoidance of anesthetics that may trigger malignant hyperthermia, and prevention of postoperative pulmonary complication. The hospital course was uncomplicated and the patient was discharged well after one day. This report emphasizes how improvements in resources, technology, and healthcare delivery, especially in anesthesia, help prevent perioperative adverse events.

BACKGROUND: Malignant hyperthermia is a potentially lethal condition triggered by specific anesthetic drugs, especially a depolarizing muscle relaxant of succinylcholine (Suxamethonium). Despite the frequent use of succinylcholine with electroconvulsive therapy (ECT), there has been no reported case of potentially lethal malignant hyperthermia following ECT. In addition, the time interval between the administration of succinylcholine and the onset of malignant hyperthermia has not been outlined in the context of ECT.
METHODS: We present the case of a 79-year-old woman suffering from severe depression, who experienced severe malignant hyperthermia due to succinylcholine administration during an ECT session. She presented with a high fever of 40.2 °C, tachycardia of 140/min, hypertension with a blood pressure exceeding 200 mmHg, significant muscle rigidity, and impaired consciousness. These symptoms emerged two hours after ECT, which occurred in a psychiatric ward rather than an operating room, and reached their peak in less than 24 h. She was given 60 mg of dantrolene, which quickly reduced the muscular rigidity. Subsequently, she received two additional doses of 20 mg and 60 mg of dantrolene, which brought her fever down to 36.2 °C and completely eased her muscle rigidity within two days after ECT.
CONCLUSIONS: This is the first reported case of potentially lethal malignant hyperthermia after ECT. In addition, it highlights the delayed onset of malignant hyperthermia following an ECT procedure, emphasizing the necessity for psychiatrists to recognize its onset even after the treatment. In the light of potentially lethal consequences of malignant hyperthermia, it is critically important for psychiatrists to closely monitor both intraoperative and postoperative patient\'s vital signs and characteristic physical presentations, promptly identify any symptomatic emergence, and treat it immediately with dantrolene.

Malignant hyperthermia (MH) is a fatal hyperthermia with a high mortality, which usually occurs during induction of general anesthesia. Dantrolene sodium is a wonder drug currently used for treating malignant hyperthermia. However, preparing, storing, and maintaining dantrolene sodium are crucially expensive, thus making it financially unsatisfactory and difficult for clinicians to acquire in time. Monitoring patients\' condition closely and intervening promptly when early signs of malignant hyperthermia occur can effectively prevent the condition from worsening and win over time for the arrival of dantraline sodium. This article is to report a case in which we successfully rescued a child occurring malignant hyperthermia without using dantrolene sodium.

Malignant hyperthermia (MH) is a rare, life-threatening condition caused by alterations in skeletal muscle calcium channels inherited through an autosomal dominant pattern. The use of specific agents in anesthesia such as inhaled anesthetics and succinylcholine can precipitate a hyperthermic crisis. Patients experience a rapid increase in muscle rigidity, secondary to skeletal muscle calcium dysregulation, leading to acute rhabdomyolysis and possible hyperthermia. Providers must have a high index of suspicion of this disease process because early diagnosis is critical to mortality reduction. Management centers around removal of the offending agent, dantrolene, and supportive care including cooling if hyperthermic. Intravascular cooling devices have been used in thermodynamic regulation after cardiac arrest and have shown to be more effective than dermal cooling techniques; however, they have not been well described in other disease processes. The following case report is the first to describe a patient suffering from MH to undergo invasive intravenous cooling in order to counteract the effects of this life-threatening disease.

Patients with neuromuscular diseases are particularly vulnerable in the perioperative period to the development of pulmonary and cardiac complications, or medication side effects. These risks could include hypoventilation, aspiration pneumonia, exacerbation of underlying cardiomyopathy, arrhythmias, adrenal insufficiency, prolonged neuromuscular blockade, issues related to thermoregulation, rhabdomyolysis, malignant hyperthermia, or prolonged mechanical ventilation. Interventions at each of the perioperative stages can be implemented to mitigate these risks. A careful pre-operative evaluation may help identify risk factors so that appropriate interventions are initiated, including cardiology consultation, pulmonary function tests, initiation of noninvasive ventilation, or implementation of preventive measures. Important intraoperative issues include positioning, airway and anesthetic management, and adequate ventilation. The postoperative period may require correction of electrolyte abnormalities, control of secretions with medications, manual or mechanical cough assistance, avoiding the risk of reintubation, judicious pain control, and appropriate medication management. The aim of this review is to increase awareness of the particular surgical challenges in this vulnerable population, and guide the clinician on the various evaluations and interventions that may result in a favorable surgical outcome.
