RESUMEN
BACKGROUND: Frostbite is defined as tissue damage that is sustained as a result of prolonged exposures to less than 0°C resulting in ice crystallisation, microvascular occlusion and subsequently thrombosis. CASE: A 33-year-old mountaineer with cold burn over 20% of the total body surface area with eschar formation, acute renal failure, upper limb venous thrombosis and bilateral pleural effusion. We hereby report a successful anaesthetic management of this patient undergoing debridement and escharotomy for frostbite injuries and review its perioperative concerns. CONCLUSION: Frostbite injuries pose a challenge to the anaesthetic team due to the multi-systemic nature of its involvement.
RESUMEN
Preeclampsia is an important cause of heart failure during pregnancy and the postpartum period. The aim of this review is to elucidate the pathophysiology and clinical features of preeclamptic heart failure and describe the medical and anesthetic management of these high-risk parturients. This article reviews the current evidence base regarding preeclamptic heart failure and its pathophysiology, types, and clinical features. We also describe the medical and anesthetic management of these patients during the peripartum period. Heart failure due to preeclampsia can present as either systolic or diastolic dysfunction. The management strategies of systolic heart failure include dietary salt restriction, diuresis, and cautious use of beta-blockers and vasodilators. Diuretics are the mainstay in the treatment of diastolic heart failure. In the absence of obstetric indications, vaginal delivery is the safest mode of delivery in these high-risk patients, and the use of an early labor epidural for analgesia is recommended. These patients would require increased invasive monitoring during labor and vaginal delivery. Neuraxial and general anesthesia have been used successfully for cesarean section in these patients but require crucial modifications of the standard technique. Uterotonic drugs have significant cardiovascular and pulmonary effects, and a clear understanding of these is essential during the management of these patients. Preeclamptics with heart failure require individualized peripartum care, as cardiac decompensation is an important risk factor for maternal and neonatal morbidity and mortality. These high-risk parturients benefit from timely multidisciplinary team inputs and collaborated management.
RESUMEN
OBJECTIVE: To determine whether enteral melatonin decreases the incidence of delirium in critically ill adults. METHODS: In this randomized controlled trial, adults were admitted to the intensive care unit and received either usual standard care alone (Control Group) or in combination with 3mg of enteral melatonin once a day at 9 PM (Melatonin Group). Concealment of allocation was done by serially numbered opaque sealed envelopes. The intensivist assessing delirium and the investigator performing the data analysis were blinded to the group allocation. The primary outcome was the incidence of delirium within 24 hours of the intensive care unit stay. The secondary outcomes were the incidence of delirium on Days 3 and 7, intensive care unit mortality, length of intensive care unit stay, duration of mechanical ventilation and Glasgow outcome score (at discharge). RESULTS: We included 108 patients in the final analysis, with 54 patients in each group. At 24 hours of intensive care unit stay, there was no difference in the incidence of delirium between Melatonin and Control Groups (29.6 versus 46.2%; RR = 0.6; 95%CI 0.38 - 1.05; p = 0.11). No secondary outcome showed a statistically significant difference. CONCLUSION: Enteral melatonin 3mg is not more effective at decreasing the incidence of delirium than standard care is in critically ill adults.

Rickets is a paediatric bone disorder characterised by defective mineralisation of bony matrix due to abnormalities in calcium and phosphate metabolism. Despite being a common disease globally, literature on the anaesthetic concerns in rickets are scant. Herein, we describe the management of a 12-year-old child with symptomatic vitamin D deficiency rickets with secondary hyperparathyroidism, undergoing general anaesthesia for an urgent orthopaedic procedure. There are numerous risks involved in such a case, such as hypocalcemia, hypophosphatemia, chest and vertebral deformities, restrictive lung disease, difficult intubation and weaning, difficult regional anaesthesia, chronic bone pain, infectious complications and postoperative decreased renal function, all of which require careful preoperative assessment and risk stratification. In elective surgeries, it is important to optimise the metabolic parameters before taking up the case. However, in urgent and emergent procedures like ours, it is imperative to take up the case after informing the parents of the risks involved.
RESUMEN
A case of Creutzfeldt-Jakob Disease (CJD), a rare prion disease, posted for surgery is a clinically challenging scenario for an anesthesiologist. In addition to weighing in the consequences of using general versus neuraxial anesthesia for a patient of such a progressive neurodegenerative disorder, the anesthesiologist must also meticulously plan and institute a robust infection control protocol, keeping in mind that prion diseases are transmissible and highly resistant to the standard sterilization process. We hereby report the successful anesthetic management of a 57-year-old patient with suspected CJD presented with intertrochanteric fracture femur for closed reduction and internal fixation and also review the existing literature regarding the anesthetic management of a definite or suspected case of CJD.

RESUMO Objetivo: Determinar se a melatonina enteral diminui a incidência de delirium em adultos em estado grave. Métodos: Neste estudo controlado e randomizado, os adultos foram admitidos à unidade de terapia intensiva e/ou receberam apenas o padrão de cuidado habitual (Grupo Controle) ou o tratamento combinado com 3mg de melatonina enteral uma vez ao dia às 21h (Grupo Melatonina). A ocultação da alocação foi feita por meio de envelopes selados opacos e numerados sequencialmente. O intensivista que avaliou o delirium e o pesquisador que realizou a análise dos dados foram cegados quanto à alocação do grupo. O desfecho primário foi a incidência de delirium dentro de 24 horas de internação na unidade de terapia intensiva. Os desfechos secundários foram a incidência de delirium nos dias 3 e 7, a mortalidade na unidade de terapia intensiva, a duração da internação na unidade de terapia intensiva, a duração da ventilação mecânica e o escore da escala de desfecho de Glasgow (na alta). Resultados: Foram incluídos 108 pacientes na análise final, com 54 sujeitos em cada grupo. Em 24 horas de internação na unidade de terapia intensiva, a incidência de delirium não foi diferente entre os Grupos Melatonina e Controle (29,6% versus 46,2%; RR = 0,6; IC95% 0,38 - 1,05; p = 0,11). Nenhum desfecho secundário apresentou diferenças estatisticamente significativas. Conclusão: Em adultos em estado grave, 3mg de melatonina enteral não foi mais eficaz que os cuidados padrão na redução da incidência de delirium.
