This report describes how postoperative delirium in an elderly man during the COVID-19 pandemic led to a serious event involving a central venous catheter. Delirium is a common cause of perioperative morbidity and mortality, and is characterised by an alteration in consciousness and perception and a reduced ability to focus, sustain, or shift attention. The event was analysed by a multidisciplinary committee, which developed a risk stratification delirium protocol in order to prevent similar events in the future.

Background and objective

Painful trigeminal neuropathy is a complex clinical entity due to its severity and refractoriness to pharmacological and interventional management. We describe our experience in treating refractory painful trigeminal neuropathy (RPTN) with Gasserian ganglion stimulation (GGS).

Materials and methods

Six patients with RPTN were treated with GGS in our unit between 2019 and 2022. The following data were collected: socio-demographic characteristics, triggering event, duration of the disease and treatment received prior to surgery, pre- and post-intervention visual analogue scale score, follow-up time, and pre- and post-intervention functionality and quality of life.

Results

All patients were women who had received aggressive first-, second-, and third-line pharmacological, non-pharmacological, and interventional management before being referred for GGS. Patients reported a 50-72% decrease in pain on visual analogue scale and improved functionality during follow-up.

Conclusions

GGS is a promising therapeutic alternative for patients with RPTN. Although the initial outcomes and experience are encouraging, RPTN is recommended on the basis of safety, reproducibility, and trends observed in clinical practice.

Background

Sarcopenia has been identified as a risk factor for perioperative adverse events. Several studies have shown that tomographic assessment of muscle mass can be an appropriate indicator of sarcopenia associated with morbidity and mortality. The aim of the study was to determine the association between height-adjusted area of the pectoral and erector spinae muscles (haPMA and haESA) and perioperative morbidity and mortality in thoracic surgery.

Methods

Retrospective cohort study. Measurement of muscle areas was performed by tomography. The outcomes were 30-day mortality and postoperative morbidity. The discriminative capacity of the muscle areas was evaluated with an analysis of ROC curves and the Youden index was used to establish a cut-off point. The raw morbidity and mortality risk was determined and adjusted for potential confounders.

Results

A total of 509 patients taken to thoracic surgery were included. The incidence of 30-day mortality was 7.3%. An association was found between muscle areas and 30-day mortality and pneumonia, with adequate discriminative power for mortality (AUC 0.68 for haPMA and 0.67 for haESA). An haPMA less than 10 and haESA less than 8.5 cm2/m2 were identified as a risk factor for 30-day mortality with an adjusted OR of 2.34 (95%CI 1.03 – 5.15) and 2.22 (95%CI 1.10 – 6.04) respectively.

Conclusions

Sarcopenia, defined as low muscle area in the pectoral and erector spinae muscles, is associated with increased morbidity and mortality in patients undergoing thoracic surgery.

We present the case of a 71-year-old woman with severe bilateral primary alveolar proteinosis admitted for bilateral whole lung lavage (WLL) with a double-lumen endotracheal tube. She had a cardiac arrest of respiratory origin during the procedure and recovered after one minute of advanced resuscitation. A second LLP was scheduled under respiratory support with veno-venous extracorporeal membrane oxygenation (VV-ECMO). During this second WLL the patient was completely VV-ECMO-dependent, and the procedure was successfully completed. She was gradually weaned over the next 48 hours. The patient was finally discharged after clinical improvement and home oxygen therapy was discontinued. WLL is the treatment of choice for severe cases of alveolar proteinosis. In rare cases the intervention may be poorly tolerated due to the degree of lung involvement. This case illustrates how VV-ECMO support is an option that may benefit this subgroup of at-risk patients.

Background

Anaesthesiology training programs in Europe vary in duration, content, and requirements for completion. This survey-based study conducted by the Trainees Committee of the European Society of Anaesthesiology and Intensive Care explores current anaesthesia training designs across Europe.

Methods

Between May and July 2018, we sent a 41-item online questionnaire to all National Trainee Representatives, members of the National Anaesthesiologists Societies Committee, and Council Representatives of the European Society of Anaesthesiology and Intensive Care (ESAIC) of all member countries. We cross-validated inconsistent data with different country representatives.

Results

Forty-three anaesthesiologists from the 39 associated ESAIC countries completed the questionnaire. Results showed considerable variability in teaching formats, frequency of teaching sessions during training, and differences in assessments made during and at the end of training. The reported duration of training was 60 months in 59% (n = 23) of participating countries, ranging from 24 months in Russia and Ukraine to 84 months in the UK.

Conclusion

This study shows the significant differences in anaesthesiology training formats across Europe, and highlights the importance of developing standardised training programs to ensure a consistent level of training and to improve patient safety. This study provides valuable insights into European anaesthesia training, and underlines the need for further research and collaboration to improve requirements.

Mean airway pressure (MAP) is the mean pressure generated in the airway during a single breath (inspiration + expiration), and is displayed on most anaesthesia and intensive care ventilators. This parameter, however, is not usually monitored during mechanical ventilation because it is poorly understood and usually only used in research. One of the main determinants of MAP is PEEP. This is because in respiratory cycles with an I:E ratio of 1:2, expiration is twice as long as inspiration. Although MAP can be used as a surrogate for mean alveolar pressure, these parameters differ considerably in some situations. Recently, MAP has been shown to be a useful prognostic factor for respiratory morbidity and mortality in mechanically ventilated patients of various ages. Low MAP has been associated with a lower incidence of 90-day mortality, shorter ICU stay, and shorter mechanical ventilation time. MAP also affects haemodynamics: there is evidence of a causal relationship between high MAP and low perfusion index, both of which are associated with poor prognosis in mechanically ventilated patients. Elevated MAP values have also been associated with high central venous pressure and lactate, which are indicative of ventilator-associated right ventricular failure and tissue hypoperfusion, respectively. MAP, therefore, is an important parameter to measure in clinical practice. The aim of this review has been to identify the determinants of MAP, the pros and cons of using MAP instead of traditional protective ventilation parameters, and the evidence that supports the use of MAP in clinical practice.

Introduction

Preoperative anemia affects approximately one third of surgical patients. It increases the risk of blood transfusion and influences short- and medium-term functional outcomes, increases comorbidities, complications and costs. The «Patient Blood Management» (PBM) programs, for integrated and multidisciplinary management of patients, are considered as paradigms of quality care and have as one of the fundamental objectives to correct perioperative anemia. PBM has been incorporated into the schemes for intensified recovery of surgical patients: the recent Enhanced Recovery After Surgery 2021 pathway (in Spanish RICA 2021) includes almost 30 indirect recommendations for PBM.

Objective

To make a consensus document with RAND/UCLA Delphi methodology to increase the penetration and priority of the RICA 2021 recommendations on PBM in daily clinical practice.

Material and methods

A coordinating group composed of 6 specialists from Hematology-Hemotherapy, Anesthesiology and Internal Medicine with expertise in anemia and PBM was formed. A survey was elaborated using Delphi RAND/UCLA methodology to reach a consensus on the key areas and priority professional actions to be developed at the present time to improve the management of perioperative anemia. The survey questions were extracted from the PBM recommendations contained in the RICA 2021 pathway. The development of the electronic survey (Google Platform) and the management of the responses was the responsibility of an expert in quality of care and clinical safety.

Participants were selected by invitation from speakers at AWGE-GIEMSA scientific meetings and national representatives of PBM-related working groups (Seville Document, SEDAR HTF section and RICA 2021 pathway participants).

In the first round of the survey, the anonymized online questionnaire had 28 questions: 20 of them were about PBM concepts included in ERAS guidelines (2 about general PBM organization, 10 on diagnosis and treatment of preoperative anemia, 3 on management of postoperative anemia, 5 on transfusion criteria) and 8 on pending aspects of research. Responses were organized according to a 10-point Likter scale (0: strongly disagree to 10: strongly agree). Any additional contributions that the participants considered appropriate were allowed. They were considered consensual because all the questions obtained an average score of more than 9 points, except one (question 14).

The second round of the survey consisted of 37 questions, resulting from the reformulation of the questions of the first round and the incorporation of the participants’ comments. It consisted of 2 questions about general organization of PBM programme, 15 questions on the diagnosis and treatment of preoperative anemia; 3 on the management of postoperative anemia, 6 on transfusional criteria and finally 11 questions on aspects pending od future investigations.
