Background

Critical COVID-19 survivors are at risk of developing Post-intensive Care Syndrome (PICS) and Chronic ICU-Related Pain (CIRP). We determined whether a specific care program improves the quality of life (QoL) of patients at risk of developing PICS and CIRP after COVID-19 disease.

Methods

The PAIN-COVID trial was a parallel-group, single-centre, single-blinded, randomized controlled trial. The intervention consisted of a follow up program, patient education on PICS and pain, and a psychological intervention based on Rehm's self-control model in patients with abnormal depression scores (> = 8) in the Hospital Anxiety and Depression Scale (HADS) at the baseline visit. QoL was evaluated with the 5-level EQ 5 D (EQ 5 D 5 L), mood disorders with the HADS, post-traumatic stress disorder (PTSD) with the PCL-5 checklist, and pain with the Brief Pain Inventory short form, the Douleur Neuropathique 4 questionnaire, and the Pain Catastrophizing Scale. The primary outcome was to determine if the program was superior to standard-of-care on the EQ visual analogue scale (VAS) at 6 months after the baseline visit. The secondary outcomes were EQ VAS at 3 months, and EQ index, CIRP incidence and characteristics, and anxiety, depression, and PTSD at 3 and 6 months after baseline visits.

Conclusions

This program was not superior to standard care in improving QoL in critical COVID-19 survivors as measured by the EQ VAS. However, our data can help establish better strategies for the study and management of PICS and CIRP in this population.

Background and objectives

The harmful effects of excess fluids frequently manifest in the lungs. Thoracic fluid content (TFC) is a variable provided by the STARLINGTM bioreactance monitor, which represents the total volume of fluid in the chest. The objective is to analyze the association between the variation in TFC values (TFCd0%) at 24 hours postoperatively, postoperative fluid balance, and postoperative pulmonary complications.

Material and methods

Prospective and analytical observational study. Patients scheduled for major abdominal surgery at a tertiary teaching hospital were included. They were monitored during the intervention and the first 24 postoperative hours with the monitor. STARLINGTM, measuring TFC and its variation in different stages of the perioperative period. Serial lung ultrasounds were performed and postoperative pulmonary complications were recorded. Logistic regression was performed to predict the occurrence of atelectasis and pulmonary congestion. The Pearson correlation coefficient was calculated to verify the association between TFC and water balance.

Results

50 patients were analyzed. TFCd0% measured on the morning of the first postoperative day increased by a median of 27.1% [IQR: 20.3-37.5] and was correlated at r = 0.44 with the postoperative balance of 677 ml [IQR: 125.5-1,412]. Increased TFC was related to a higher risk of atelectasis (OR = 1.24) and pulmonary congestion (OR = 1.3).

Conclusions

TFCd0% measured 24 hours after surgery presents a moderate correlation with postoperative fluid balance. Its increase is a risk factor for the appearance of postoperative pulmonary complications.

Recent publications have questioned the efficacy of using therapeutic or intermediate doses of low molecular weight heparin (LMWH) in COVID-19 patients, especially in the most severe patients. In order to update these recommendations, a non-systematic review has been carried out in the main medical databases. A total of 14 randomized clinical trials, 14 meta-analyses and the recommendations of 12 scientific societies were selected, stratified according to the type of patient (outpatient, hospitalized, admitted to critical care or post-discharge). The efficacy of LMWH and other therapeutic approaches (rivaroxaban, apixaban, sulodexide, acetylsalicylic acid and P2Y12 inhibitors) has been analyzed. The findings recommend using standard doses of LMWH as thromboprophylaxis in critically hospitalized COVID-19 patients and therapeutic doses in non-critically hospitalized patients with low bleeding risk. In outpatients and those discharged from the hospital, LMWH could be used at a prophylactic dose if there are thrombotic risk factors, and the bleeding risk is low. It is not recommended to associate antiplatelet agents with LMWH unless previously indicated.

Objective

The objective of our study was to compare the degree of difficulty and complications related to tracheal intubation in an intensive care unit (ICU) before and after the introduction of an intubation protocol based on the Difficult Airway Society guidelines for the management of tracheal intubation in critically ill adults, published in 2018.

Methods

Prospective, observational study comparing all intubations performed in our ICU over two periods: pre-protocol (January 2015-January 2019) and post-protocol (February 2019-July 2022). The material used for intubation, the degree of difficulty, and intubation-related complications were recorded.

Results

During the study period, 661 patients were intubated —437 in the pre-protocol period (96% by direct laryngoscopy) and 224 in the post-protocol period (53% with direct laryngoscopy, 46% with video laryngoscopy). We observed an improvement in laryngeal view in the post-protocol period compared to the pre-protocol period (Cormack-Lehane ≥ 2b in 7.6% vs 29.8%, P < .001), and a decrease in the number of moderate-to-severely difficult intubations (6.7% vs 17.4%, P < .001). The first-pass success rate was 92.8% in the post-protocol period compared to 90.2% pre-protocol (P = .508). We did not find significant differences in complications between the periods studied.

Conclusions

Intubations performed in the post-protocol period were associated with improved laryngeal view and fewer cases of difficult intubation compared with the pre-protocol period.

Introduction

Arrhythmic storm is a life-threatening emergency with a high mortality rate. When acute conventional treatment is ineffective, a stellate ganglion block can contribute to the control of the arrhythmia by providing a visceral cervicothoracic sympathetic block. The objective of the study is to assess the effectiveness and safety of stellate ganglion blocks for the treatment of refractory arrhythmic storm.

Method

Follow-up of a cohort of patients with refractory arrhythmic storm that met the criteria for performing stellate ganglion blocks. The block was ultrasound-guided at C6-level using local anaesthetic and a steroid, left unilateral first, bilateral if no response, and followed by fluoroscopy-guided radiofrequency ablation at C7 if there was a favourable response but subsequent relapse.

Results

Seven patients were included, with a mortality rate during admission of 14.29%. Four patients received unilateral and three bilateral stellate ganglion blocks. Six were ablated and one of them had an implanted cardioverter-defibrillator. Arrhythmic storm was controlled temporarily beyond the effect of the local anaesthetic in all patients. Three underwent radiofrequency ablation and two underwent surgical thoracic sympathectomy. The only side effect was Horner's syndrome, which was observed in all cases after administering a stellate ganglion block with local anaesthetic. Two died after discharge and four are still at home, three of them without further admission due to ventricular events for more than two years.

Conclusion

An ultrasound-guided stellate ganglion block is an effective and safe technique in the treatment of refractory arrhythmic storm as a complement to the usual cardiological treatment.

Medical consult and follow-up of patients have been carried out remotely for years. During the COVID-19 pandemic, different societies have recommended promoting online consultations. The remote pre-anesthetic consultation is a medical act that must include the basic objectives of evaluation, preparation, information and obtaining consent. You must have the resources and time to do it. At the beginning of the consultation, the doctor and the parent(s) must be identified. Non-face-to-face preoperative consultation is especially useful in ASA I and II children evaluated for low-risk surgeries, reintervention, or diagnostic procedures. Those patients who require a physical examination, beyond that possible electronically, should make an appointment in the face-to-face consultation. The nursing staff can actively participate in this process as long as the anesthesiologist supervises the entire process, makes all decisions about the procedure and is responsible for the information given to the parents and the child, personally clarifying any doubts. The anesthesiologist must inform about the procedure, its risks, including personalized ones, and alternatives. It will be recorded in the medical history the information given, when and to whom. The anesthesiologist will sign the Informed Consent stating the date that the information is given, and the parents must sign it before the intervention.

Video-assisted thoracoscopy (VATS) cardiac surgery requires one-lung ventilation (OLV) and transoesophageal ultrasound (TOE) monitoring. Colour and spectral Doppler make it possible to study the pattern of blood flow in the pulmonary vessels within the atelectatic lung. In this case report we describe how TOE can be used to detect blood flow within the atelectatic lung and to assess pulmonary vascular resistance (PVR) and right ventricular afterload.

Findings

Three anaesthetised, mechanically ventilated adults scheduled for VATS cardiac surgery were monitored using TOE. After left OLV, the transducer was rotated away from the heart to obtain 2D colour Doppler images of blood flow within the consolidated lung parenchyma. We were able to identify the flow pattern of the intrapulmonary branches of the pulmonary artery. PVR was recorded using pulsed cardiac Doppler at baseline, after induction of general anaesthesia, 20 min after OLV and at the end of OLV, and after performing an alveolar recruitment manoeuvre (ARM) that led to complete resolution of the aforementioned consolidation.

Conclusions

TOE is a semi-invasive imaging tool that can be used to diagnose and study PVR-induced atelectasis and to analyse the resulting pulmonary shunt and its possible effect on PVR.

Objective

To analyse the impact of 10 years of blended echocardiography teaching.

Methods and results

A questionnaire was emailed to all medical doctors who graduated from the blended learning diploma in echocardiography developed by the University of Chile and taught by a team from Chile and Spain. One hundred and forty of the 210 students who graduated from the program between 2011 and 2020 completed the questionnaire: 53.57% were anaesthesiologists, and 26.42% were intensivists. More than 85% of respondents indicated that the online teaching met their expectations, and 70.2% indicated that the hands-on practice fulfilled the stated objectives. In a retrospective analysis using self-reported data, graduates reported that their use of transthoracic and transoesophageal echocardiography has increased from 24.29% to 40.71% and from 13.57% to 27.86%, repectively, after the programme compared to before the programme. They used echocardiography mainly in the perioperative period (56.7%) and during intensive care (32.3%), while only 11% of respondents used it in emergency care units. Nearly all (92.4%) respondents reported that the skills learned was very useful in their professional practice.

Conclusions

Ten years after its launch, the blended learning diploma in echocardiography was well rated by graduate specialists, and is associated with a significant increase in the use of echocardiography in the perioperative period and during intensive care. The main challenges are to establish a longer period of practice and achieve greater implantation in emergency medicine.
