Electrical impedance tomography is a new method of monitoring non-invasive mechanical ventilation, at the bedside and useful in critically ill patients. It allows lung monitoring of ventilation and perfusion, obtaining images that provide information on lung function. It is based on the physical principle of impedanciometry or the body's ability to conduct an electrical current. Various studies have shown its usefulness both in adults and in pediatrics in respiratory distress syndrome, pneumonia and atelectasis in addition to pulmonary thromboembolism and pulmonary hypertension by also providing information on pulmonary perfusion, and may be very useful in perioperative medicine; especially in pediatrics avoiding repetitive imaging tests with ionizing radiation.

The PENG block (Pericapsular Nerve Group) is a recently described technique to address the innervation of the hip, one of the most complex anatomical regions to treat at the locoregional level.

We present the case of a patient with acute lymphoblastic leukemia complicated by avascular necrosis of the bilateral femoral head and previous history of severe chronic pain with probable central sensitization to opioids and a severe thrombocytopenia due to myelotoxicity from chemotherapy treatment.

Given the need for orthopedic surgery to manage femoral necrosis and in anticipation of complex perioperative pain management, a multimodal strategy was planned including bilateral ultrasound-guided continuous PENG blocks to achieve proper pain control in the perioperative period and promote early recovery. The operation and initial recovery were uneventful and the patient was discharged to the ward within 24 h and started early rehabilitation as planned. The patient had a successful recovery with good functionality.

Dexmedetomidine's α-adrenoreceptor agonism has been gaining popularity in the anesthetic room as a sedative-hypnotic and analgesic agent, and with extensive perioperative use rising concern about side effects is necessary.

Bradycardia and hypotension are common but excessive urine output is increasingly reported, suggested mechanisms being vasopressin secretion and increasing permeability of the collecting ducts.

Polyuria usually resolves with discontinuation of the drug and significant morbidity has not been reported. Early identification, removal of agent and treatment are imperative to minimize complications, mainly associated with natremia levels and neurological symptoms.

This case report describes a dexmedetomidine-related polyuric syndrome during opioid-free general anesthesia for major head and neck surgery. A nephrogenic mechanism for the clinical effect is proposed and reinforced by analytical data obtained. An intra-operative polyuria approach is also delineated.

Introduction and objectives

Cataract surgery is one of the most common procedures in outpatient surgery units. The use of information and communication technologies (ICT) in clinical practice and the advent of new health scenarios, such as the Covid pandemic, have driven the development of pre-anaesthesia assessment models that free up resources to improve access to cataract surgery without sacrificing patient safety. The approach to cataract surgery varies considerably among public, subsidised and private hospitals. This raises the need for guidelines to standardise patient assessment, pre-operative testing, management of background medication, patient information and informed consent.

Results

In this document, the SEDAR Clinical Management Division together with the Major Outpatient Surgery Division put forward a series of consensus recommendations on pre-anaesthesia testing based on the use of ITCs, health questionnaires, patient information, and informed consent supervised and evaluated by an anaesthesiologist.

Conclusions

This consensus document will effectivise pre-anaesthesia assessment in cataract surgery while maintaining the highest standards of quality, safety and legality.

The main causes of maternal mortality are comorbidities, hypertensive pregnancy syndrome, obstetric haemorrhage, and maternal sepsis. For this reason, uterotonics, magnesium sulphate, and antibiotics are essential tools in the management of obstetric patients during labour and in the peripartum period. These drugs are widely used by anaesthesiologists in all departments, and play a crucial role in treatment and patient safety.

For the purpose of this narrative review, we performed a detailed search of medical databases and selected studies describing the use of these drugs in patients during pregnancy, delivery and the pospartum period.

Uterotonics, above all oxytocin, play an important role in the prevention and treatment of pospartum haemorrhage, and various studies have shown that in obstetric procedures, such as scheduled and emergency caesarean section, they are effective at lower doses than those hitherto accepted. We also discuss the use of carbetocin as an effective alternative that has a therapeutic advantage in certain clinical circumstances.

Magnesium sulphate is the gold standard in the prevention and treatment of eclampsia, and also plays a neuroprotective role in preterm infants. We describe the precautions to be taken during magnesium administration.

Finally, we discuss the importance of understanding microbiology and the pharmacology of antibiotics in the management of obstetric infection and endometritis, and draw attention to the latest trends in antibiotic regimens in labour and caesarean section.

Background

Continuous peripheral nerve blocks are commonly used for pain management. However, the incidence of catheter dislodgement or migration is unclear, and may be underestimated and underreported. Our objective was to assess suprascapular catheter tip positioning before and after routine simulated shoulder physiotherapy manipulation in an anatomical cadaver model.

Method

Eight ultrasound-guided continuous suprascapular nerve block catheters were placed in cryopreserved fresh cadavers. Computed tomography (CT) confirmed the location of the catheter tip after injection of 1 ml of contrast medium. We performed a series of standardized shoulder movements during a simulated shoulder physiotherapy session in cadavers. Following this, we administered 1 ml of methylene blue through the catheters, and then performed anatomical dissections to accurately identify the location of the catheter tips and compare them to their placement prior to the ‘physiotherapy’

Result

CT imaging confirmed the location of the catheter tips at the suprascapular notch in all cases. However, following physiotherapy, 2 catheters (25%) were found to have migrated - specifically, 1 was located in the supraspinatus muscle, and the other was located in the trapezius muscle.

Conclusion

Our findings suggest that catheter dislodgement may occur in approximately 25% of cases following simulated physiotherapy manipulation. However, further research is needed to determine the read incidence of catheter dislodgement in clinical practice.

Objective

To identify the first symptoms and signs of patients with suspected infection or sepsis and their association with the composite outcome of admission to the intensive care unit or mortality.

Design

Prospective cohort study between June 2019 and March 2020.

Setting

Hospital Universitario San Vicente Fundación, Colombia.

Patients

Over 18 years of age with suspicion or confirmation of sepsis, which required hospitalization.

Interventions

None.

Main variables of interest

Symptoms and signs associated with infection, with their time of evolution, specified in the study.

Results

From 1005 eligible patients, 261 were included. After multivariable adjustment with a logistic regression model, the main factors for intensive care unit admission or mortality were heart rate (OR 1.04 with 95% CI 1.04-3.7), respiratory rate (OR 1.19 with 95% CI 1.0-1.4) and capillary refill time (OR 3.4 with 95% CI 1.9-6.1).

Conclusions

Heart rate, respiratory rate, and capillary refill may behave as early predictors of intensive care unit admission and mortality in cases of sepsis.

Introduction and objectives

Sedation is used in intensive care units (ICU) to improve comfort and tolerance during mechanical ventilation, invasive interventions, and nursing care. In recent years, the use of inhalation anaesthetics for this purpose has increased. Our objective was to obtain and summarize the best evidence on inhaled sedation in adult patients in the ICU, and use this to help physicians choose the most appropriate approach in terms of the impact of sedation on clinical outcomes and the risk-benefit of the chosen strategy.

Methodology

Given the overall lack of literature and scientific evidence on various aspects of inhaled sedation in the ICU, we decided to use a Delphi method to achieve consensus among a group of 17 expert panellists. The processes was conducted over a 12-month period between 2022 and 2023, and followed the recommendations of the CREDES guidelines.

Results

The results of the Delphi survey form the basis of these 39 recommendations - 23 with a strong consensus and 15 with a weak consensus.

Conclusion

The use of inhaled sedation in the ICU is a reliable and appropriate option in a wide variety of clinical scenarios. However, there are numerous aspects of the technique that require further study.

Kounis syndrome is defined as cardiovascular symptoms that occur secondary to allergic or hypersensitivity insults, and is also called allergic angina and allergic myocardial infarction. We report a case of pre-operative ceftriaxone-induced Kounis syndrome with no evident dermatological manifestation, and describe our diagnostic dilemma. The patient was symptomatically managed and discharged in stable condition with a warning against future use of ceftriaxone.
