ABSTRACT

Telehealth appears useful to fill in the void for home-ventilated patients to maintain the much-needed connectivity with their healthcare team during the #COVID19 pandemic https://bit.ly/3ftvjxW.

ABSTRACT

BACKGROUND: In Singapore, a dedicated adult multidisciplinary Home Ventilation and Respiratory Support Service (HVRSS) was set-up to assist individuals with chronic ventilatory failure. We aimed to study the use, survival outcomes and identify factors influencing survival in our cohort of ventilator-assisted individuals (VAIs). METHODS: We retrospectively reviewed all referrals to HVRSS from 2009 to 2015. All VAIs were included and divided into 4 categories: (I) amyotrophic lateral sclerosis (ALS); (II) other neuromuscular and chest wall disease (NMCW); (III) spinal cord injury (SCI); and (IV) complex intensive care unit (ICU) groups for comparison of baseline characteristics, co-morbidities, therapy details and survival outcomes. Cox proportional analysis was used to identify important factors influencing survival for ALS and non-ALS VAIs. RESULTS: There were 112 VAIs; most were male (63%) and ethnic Chinese (83%). At baseline, median [interquartile range (IQR)] age was 61 [46-69] years, body mass index was 20.2 (17.1-23.8) kg/m2 and forced vital capacity was 38 [24-65] %predicted. The three most common diseases were ALS (43%), SCI (13%) and congenital muscular dystrophies (6%). Seventy-four (66%) VAIs received non-invasive ventilation (NIV). Median survival for ALS, Complex ICU, SCI and NMCW VAIs were 1.8, 2.6, 4.2 and 6.7 years respectively. In ALS, NIV conversion to invasive mechanical ventilation (IMV) was associated with longer survival [hazard ratio (HR) 0.24]. In non-ALS VAIs, older age (HR 1.40) and cardiovascular comorbidities (HR 2.61) were poor prognostic factors. CONCLUSIONS: The HVRSS managed a heterogenous group of VAIs in Singapore and survival is comparable to published cohorts. ALS had the worst survival whereas NMCW had the best survival with Complex ICU and SCI groups in between. Transition from NIV to IMV, age and cardiovascular disease were important prognostic factors.

ABSTRACT

INTRODUCTION: Awake craniotomy allows accurate localisation of the eloquent brain, which is crucial during brain tumour resection in order to minimise risk of neurologic injury. The role of the anaesthesiologist is to provide adequate analgesia and sedation while maintaining ventilation and haemodynamic stability in an awake patient who needs to be cooperative during neurological testing. We reviewed the anaesthetic management of patients undergoing an awake craniotomy procedure. MATERIALS AND METHODS: The records of all the patients who had an awake craniotomy at our institution from July 2004 till June 2006 were reviewed. The anaesthesia techniques and management were examined. The perioperative complications and the outcome of the patients were noted. RESULTS: There were 17 procedures carried out during the study period. Local anaesthesia with moderate to deep sedation was the technique used in all the patients. Respiratory complications occurred in 24% of the patients. Hypertension was observed in 24% of the patients. All the complications were transient and easily treated. During cortical stimulation, motor function was assessed in 16 patients (94%). Three patients (16%) had lesions in the temporal-parietal region and speech was assessed intraoperatively. Postoperative motor weakness was seen in 1 patient despite uneventful intraoperative testing. No patient required intensive care unit stay. The median length of stay in the high dependency unit was 1 day and the median length of hospital stay was 9 days. There was no in-hospital mortality. CONCLUSION: Awake craniotomy for brain tumour excision can be successfully performed under good anaesthetic conditions with careful titration of sedation. Our series showed it to be a well-tolerated procedure with a low rate of complications. The benefits of maximal tumour excision can be achieved, leading to potentially better patient outcome.

ABSTRACT

CONTEXT: Severe acute respiratory syndrome (SARS) is an emerging infectious disease with a 25% incidence of progression to acute lung injury (ALI)/acute respiratory distress syndrome (ARDS) and mortality exceeding 10%. OBJECTIVE: To describe the clinical spectrum and outcomes of ALI/ARDS in patients with SARS-related critical illness. DESIGN, SETTING, AND PATIENTS: Retrospective case series of adult patients with probable SARS admitted to the intensive care unit (ICU) of a hospital in Singapore between March 6 and June 6, 2003. MAIN OUTCOME MEASURES: The primary outcome measure was 28-day mortality after symptom onset. RESULTS: Of 199 patients hospitalized with SARS, 46 (23%) were admitted to the ICU, including 45 who fulfilled criteria for ALI/ARDS. Mortality at 28 days for the entire cohort was 20 (10.1%) of 199 and for ICU patients was 17 (37%) of 46. Intensive care unit mortality at 13 weeks was 24 (52.2%) of 46. Nineteen of 24 ICU deaths occurred late (> or =7 days after ICU admission) and were attributed to complications related to severe ARDS, multiorgan failure, thromboembolic complications, or septicemic shock. ARDS was characterized by ease of derecruitment of alveoli and paucity of airway secretion, bronchospasm, or dynamic hyperinflation. Lower Acute Physiology and Chronic Health Evaluation II scores and higher baseline ratios of PaO2 to fraction of inspired oxygen were associated with earlier recovery. CONCLUSIONS: Critically ill patients with SARS and ALI/ARDS had characteristic clinical findings, high rates of complications; and high mortality. These findings may provide useful information for optimizing supportive care for SARS-related critical illness.
