Special considerations for the management of COVID-19 pediatric patients in the operating room and pediatric intensive care unit in a tertiary hospital in Singapore.

COVID-19 was first identified in Wuhan, China and is caused by the novel coronavirus SARS-CoV 2. It has now spread rapidly to over 190 countries and territories around the world and has been declared a global pandemic by the World Health Organization. The virus is spread through droplet transmission and currently has a mortality rate of over 4% globally. The pediatric population has been found to be less susceptible to the disease with the majority of children having milder symptoms and only one pediatric death being reported globally so far. Despite this, strategies need to be put in place to prevent further spread of the virus. We present a summary of the general measures implemented at a large adult and pediatric tertiary hospital in Singapore (National University Hospital) as well as the specific strategies in place for the operating room and pediatric intensive care unit.

Intrathecal dexmedetomidine and postoperative pain: A systematic review and meta-analysis of randomized controlled trials.

BACKGROUND AND OBJECTIVE: A systematic review and meta-analysis of randomized controlled trials (RCTs) was undertaken to evaluate the effect of intrathecal dexmedetomidine (DEX) on the duration of postoperative analgesia, postoperative pain scores and incidences of adverse effects. DATABASES AND DATA TREATMENT: Database search was performed from inception until January 2019. All RCTs analysing acute postoperative pain characteristics after intrathecal DEX administration in adults undergoing spinal anaesthesia for elective surgery were included. The primary outcome was postoperative analgesic duration, defined as the time to first analgesic request. The secondary outcomes included pain scores at 6, 12 and 24 postoperative hours and rates of hypotension, bradycardia, shivering and postoperative nausea and vomiting. RESULTS: Twenty-four studies comprising a total of 1,460 patients were included. Postoperative analgesic duration was prolonged with intrathecal DEX compared to placebo, with a pooled mean difference (MD) of 191.3 min (95% CI 168.8-213.8). Patients who received intrathecal DEX reported lower Visual Analogue Scale scores at 24 postoperative hours compared with those patients receiving placebo, with a MD (95% CI) of -1.05 (-1.89 to -0.20, p = 0.02). There were no differences in the incidence of adverse effects, except for a lower rate of postoperative shivering in the intrathecal DEX group (pooled relative risk 0.58, 95% CI 0.34-0.98, p = 0.04). CONCLUSIONS: Compared to placebo, intrathecal DEX prolonged postoperative analgesic duration, reduced 24-hr pain intensity and reduced the incidence of shivering without an increase in other adverse effects. SIGNIFICANCE: The analgesic role of intrathecal DEX is promising due to its ability to significantly increase postoperative analgesic duration when compared with placebo. Its usage can be considered for patients undergoing surgeries with significant postoperative pain, particularly those intolerant of systemic analgesia. However, the optimal dose for various surgeries as well as its long-term neurological effects warrants further studies.

Correction to: Anesthetic technique and cancer outcomes: a meta-analysis of total intravenous versus volatile anesthesia.

There was an isolated error relating to the Oh et al. study (1) within our recurrence-free survival analysis. When the reported estimates for Oh et al. are corrected, the pooled hazard ratio (HR) is now 0.87; 95% confidence interval (CI), 0.66 to 1.15; P=0.32.

Anesthetic technique and cancer outcomes: a meta-analysis of total intravenous versus volatile anesthesia.

PURPOSE: Cancer-related mortality, a leading cause of death worldwide, is often the result of metastatic disease recurrence. Anesthetic techniques have varying effects on innate and cellular immunity, activation of adrenergic-inflammatory pathways, and activation of cancer-promoting cellular signaling pathways; these effects may translate into an influence of anesthetic technique on long-term cancer outcomes. To further analyze the effects of propofol (intravenous) and volatile (inhalational gas) anesthesia on cancer recurrence and survival, we undertook a systematic review with meta-analysis. SOURCE: Databases were searched up to 14 November 2018. Comparative studies examining the effect of inhalational volatile anesthesia and propofol-based total intravenous anesthesia (TIVA) on cancer outcomes were included. The Newcastle Ottawa Scale (NOS) was used to assess methodological quality and bias. Reported hazard ratios (HRs) were pooled and 95% confidence intervals (CIs) calculated. PRINCIPAL FINDINGS: Ten studies were included; six studies examined the effect of anesthetic agent type on recurrence-free survival following breast, esophageal, and non-small cell lung cancer (n = 7,866). The use of TIVA was associated with improved recurrence-free survival in all cancer types (pooled HR, 0.78; 95% CI, 0.65 to 0.94; P < 0.01). Eight studies (n = 18,778) explored the effect of anesthetic agent type on overall survival, with TIVA use associated with improved overall survival (pooled HR, 0.76; 95% CI, 0.63 to 0.92; P < 0.01). CONCLUSION: This meta-analysis suggests that propofol-TIVA use may be associated with improved recurrence-free survival and overall survival in patients having cancer surgery. This is especially evident where major cancer surgery was undertaken. Nevertheless, given the inherent limitations of studies included in this meta-analysis these findings necessitate prospective randomized trials to guide clinical practice.

RéSUMé: OBJECTIF: La mortalité liée au cancer, une cause majeure de décès dans le monde entier, est bien souvent le résultat de la récurrence de la maladie métastatique. Les techniques anesthésiques ont des effets variés sur l'immunité naturelle et cellulaire, l'activation des voies adrénergiques inflammatoires, et l'activation des voies de signalisation cellulaire promouvant le cancer; ces effets pourraient se traduire dans une influence de la technique anesthésique sur les pronostics de cancer à long terme. Afin d'approfondir l'analyse des effets de l'anesthésie au propofol (voie intraveineuse) et par inhalation (gaz) sur la récurrence du cancer et la survie, nous avons entrepris une revue systématique avec méta-analyse. SOURCE: Nous avons réalisé des recherches dans les bases de données jusqu'au 14 novembre 2018. Les études comparatives examinant l'effet d'une anesthésie par inhalation et d'une anesthésie intraveineuse totale (TIVA) avec propofol sur les pronostics de cancer ont été incluses dans notre revue. L'échelle de Newcastle-Ottawa (NOS) a été utilisée pour évaluer la qualité méthodologique et le biais. Les rapports de risque (RR) rapportés ont été pondérés et les intervalles de confiance (IC) à 95 % calculés. CONSTATATIONS PRINCIPALES: Dix études ont été incluses; six études ont examiné l'effet du type d'agent anesthésique sur la survie sans récurrence après un cancer du sein, de l'œsophage et du cancer pulmonaire non à petites cellules (n = 7866). L'utilisation d'une TIVA était associée à une amélioration de la survie sans récurrence, tous types de cancer confondus (RR pondéré, 0,78; IC 95 %, 0,65 à 0,94; P < 0,01). Huit études (n = 18 778) ont exploré l'effet du type d'agent anesthésique sur la survie globale, l'utilisation d'une TIVA étant alors associée à une amélioration de la survie globale (RR pondéré, 0,76; IC 95 %, 0,63 à 0,92; P < 0,01). CONCLUSION: Cette méta-analyse suggère que l'administration d'une TIVA à base de propofol pourrait être associée à une amélioration de la survie sans récurrence et de la survie globale chez les patients subissant une chirurgie oncologique. Cette observation est particulièrement frappante dans les cas de chirurgie oncologique majeure. Toutefois, étant donné les lacunes inhérentes des études incluses dans cette méta-analyse, ces résultats nécessitent la réalisation d'études randomisées prospectives afin d'éclairer la pratique clinique.

Spiritual belief, social support, physical functioning and depression among older people in Bulgaria and Romania.

OBJECTIVES: An exploratory investigation is reported into the role of spirituality and religious practice in protecting against depression among older people living in rural villages in Bulgaria and Romania, two neighbouring countries with similar cultural, political and religious histories, but with differing levels of current religiosity. METHODS: In both countries, interviews were conducted with samples of 160 persons of 60 years and over in villages of similar socio-economic status. The Hospital Anxiety and Depression-D scale and the Royal Free Interview for Religious and Spiritual Beliefs were used to assess depression and spiritual belief and practice respectively. In addition social support, physical functioning and the presence of chronic diseases were assessed. One year later, follow-up interviews were conducted with 58 of the original sample in Bulgaria, in which additional measures of depression and of spiritual belief and practice were also included. RESULTS: The study demonstrates, as expected, significantly lower levels of spiritual belief in the Bulgarian sample (Bulgarian mean 29.7 (SD = 19.1), Romanian mean 47.6 (SD = 11.2), t = 10.2, p < 0.001), as well as significantly higher levels of depression (Bulgarian mean 12.0 (SD = 4.9), Romanian mean 7.3 (SD = 4.1), t = 9.3, p < 0.001), the latter attributable in large part to higher morbidity and disability rates, but less evidently to differences in strength of belief. However, analyses from both the cross-sectional study and the one-year follow-up of the Bulgarian sample do suggest that spiritual belief and practice may both influence and reflect physical and mental illness. CONCLUSIONS: Much of Eastern Europe displays high rates of depression among its older population and provides opportunities for investigation of the role of religious belief and practice in preventing and coping with depression. Further research is encouraged in populations of diverse religiosity.
