Patient-controlled Analgesia with Remifentanil in a Parturient with Ankylosing Spondylitis and SARS-CoV-2 Infection: A Case Report.

Parturients with both ankylosing spondylitis (AS) and SARS-CoV-2 Infection (COVID-19) present unique challenges to anesthesiologists. Neuraxial analgesia for labor remains the gold standard in obstetric patients. However, in patients with AS, this approach may be deemed difficult to impossible. Administration of systemic opioids for labor analgesia can be an option, bearing in mind the potential respiratory depressant effect to both the mother and the fetus, especially in the setting of concomitant COVID-19. This paper reports the successful management of such a patient using patient-controlled analgesia (PCA) with intravenous remifentanil.

Sertraline hydrochloride for reducing impulsive behaviour in male, repeat-violent offenders (ReINVEST): protocol for a phase IV, double-blind, placebo-controlled, randomised clinical trial.

INTRODUCTION: Considerable evidence supports an association between poor impulse control (impulsivity) and violent crime. Furthermore, impulsivity and aggression has been associated with reduced levels of serotonergic activity in the brain. Selective serotonin reuptake inhibitors (SSRIs) are a class of anti-depressants that aim to regulate brain serotonin concentrations. Several small studies in psychiatric populations have administered SSRIs to impulsive--aggressive individuals, resulting in reduced impulsivity, anger, aggression and depression. However, no clinical trial has been undertaken in a criminal justice population. This protocol describes the design and implementation of the first systematic study of the potential benefits of SSRIs in impulsive---violent offenders who are at high risk of reoffending. METHODS AND ANALYSIS: A randomised, double-blinded, multicentre trial to test the clinical efficacy of an SSRI, sertraline hydrochloride, compared with placebo on recidivism and behavioural measures (including impulsivity, anger, aggression, depression and self-reported offending) over 12 months. 460 participants with histories of violence and screening positive for impulsivity are recruited at several local courts and correctional service offices in New South Wales, Australia. ETHICS AND DISSEMINATION: Results will be submitted for publication in a peer-reviewed journal. Possible implications of the effectiveness of this pharmacological intervention include economic benefits of reducing prison costs and societal benefits of improving safety. This study has received ethical approval from the University of New South Wales, Aboriginal Health & Medical Research Council, Corrective Services NSW and the NSW Justice Health and Forensic Mental Health Network.

Narcotrend-guided intraoperative care of a Trisomy 21 paediatric patient who underwent occipitocervical fusion.

A 9-year-old female with Trisomy 21 with complex craniovertebral instability causing severe cervicomedullary compression underwent occipitocervical fusion. This paper will discuss the anaesthetic management and highlight the use of the Narcotrend monitor not only as a depth of consciousness monitor but more importantly as a tool to detect surgery-induced cerebral hypoperfusion by monitoring the right and left cerebral hemispheres independently and simultaneously.
