The intertransverse process block single- or multiple-injection? A study protocol.
Intertransverse process (ITP) blocks are applied on the posterior side of the thoracic paravertebral space. The modality is described as being a paravertebral block by proxy, possibly providing a similar analgesic effect as the thoracic paravertebral block. However, systematic evidence on anaesthetised dermatomes and the extent of cutaneous sensory loss following ITP blocks is sparse. This study aims to test the single- versus the multiple-injection ITP block. The primary outcome is the number of anaesthetised thoracic dermatomes for each block type. ⋯ The current study will provide substantial knowledge regarding the cutaneous sensory loss of the ITP block. Furthermore, the study might provide insight regarding the possible clinical usage of thermography as a reliable instrument for measuring nerve block efficacy.

Observational StudyPleural effusion and thoracentesis in ICU patients: A longitudinal observational cross-sectional study.
Pleural effusion is common among patients in the intensive care unit (ICU) but reported prevalence varies. Thoracentesis may improve respiratory status, however, indications for this are unclear. We aimed to explore prevalence, development, and progression of pleural effusion, and the incidence and effects of thoracentesis in adult ICU patients. ⋯ Pleural effusion was common in the ICU, but less than half of all patients with ultrasonographically significant pleural effusion underwent thoracentesis. Progression of pleural effusion without thoracentesis showed reduced volumes on subsequent days.

Association of sleep and anaesthesia EEG biomarkers with preoperative MoCA score: A pilot study.
Preoperative cognitive impairments increase the risk of postoperative complications. The electroencephalogram (EEG) could provide information on cognitive vulnerability. The feasibility and clinical relevance of sleep EEG (EEGsleep ) compared to intraoperative EEG (EEGintraop ) in cognitive risk stratification remains to be explored. We investigated similarities between EEGsleep and EEGintraop vis-a-vis preoperative cognitive impairments. ⋯ Preoperative cognitive impairment appears to be detectable by both EEGsleep and EEGintraop . Preoperative sleep EEG to assess perioperative cognitive risk is feasible but more data are needed to demonstrate its benefit compared to intraoperative EEG.

Clinical TrialThe haemodynamic effects of phenylephrine after cardiac surgery.
Phenylephrine increases systemic- and pulmonary resistances and therefore may increase blood pressures at the expense of blood flow. Cardio-pulmonary bypass alters vasoreactivity and many patients exhibit chronotropic insufficiency after cardiac surgery. We aimed to describe the haemodynamic effects of phenylephrine infusion after cardiac surgery. ⋯ clinicaltrial.gov (identifier NCT04419662).

Perioperative management of patients declining transfusions of blood components-National survey of anaesthesiologists, abdominal surgeons and obstetricians in Denmark.
Perioperative management of patients declining transfusions of blood products can be challenging both ethically and clinically. Jehovah's Witnesses (JW) decline treatment with blood products and have published a list of interventions they might accept as substitutes. No detailed documentation of available substitute interventions at Danish hospitals exists. ⋯ Depending on the type of anticoagulant, between 31 (32%) and 59 (60%) of respondents reported locally available guidelines for reverting anticoagulant treatments. We found a considerable variation and limited availability of interventions to minimise blood loss in patients declining transfusion of blood components. This scarcity of local guidelines together with the considerable variation of available treatment documented in our survey could possibly be enhanced by a lack of national guidelines.
