Perioperative implications of pericardial effusions and cardiac tamponade

Awake uniportal video-assisted thoracoscopic surgery for the management of pericardial effusion

Introduction

Pericardial drainage can be performed either with pericardiocentesis or pericardial "window" in cases with hemodynamic compromise for therapeutic and diagnostic purposes. Awake single-port video-assisted thoracoscopic surgery (VATS) is an alternative to pericardial window (PW) that has been described only in case reports in the literature. We aimed to analyse a series of patients with chronic, recurrent and/or large pericardial effusions who underwent single-port VATS-PW opening without intubation.

Patients and Methods

The PW was opened using awake single-port VATS in 20 of 23 patients referred to our clinic with recurrent, chronic and/or large pericardial effusion between December 2021 and July 2022. Demographic data, imaging modalities, treatment processes and pathological samples were analysed retrospectively.

Results

The median age of 20 patients was 68 years (52-81). The mean body mass index was 29.1 ± 6.0 kg/m2 and mean pericardial fluid measurements with pre-operative transthoracic echocardiography (TTE) was 2,8 ± 0,9 cm. The mean operation time was 44 ± 13.0 min and mean peri-operative drainage was 700 ± 307 cc. On the 1st post-operative day, control TTE revealed ≤0.5 cm effusion in 18 (90%) patients and ≥0.5 cm in 2 (10%) patients. The median day of discharge or referral to the clinic where they are followed up was 1 (1-2).

Conclusions

Awake single-port VATS could be used safely in all patient groups with pericardial effusion or tamponade as a diagnostic and therapeutic option. This technique has advantages, especially in patients with high surgical risk.

Approach to the Physiologically Challenging Endotracheal Intubation in the Intensive Care Unit

Endotracheal intubation for airway management is a common procedure in the ICU. Intubation may be difficult due to anatomic airway abnormalities but also due to physiologic derangements that predispose patients to cardiovascular collapse during the procedure. Results of studies demonstrate a high incidence of morbidity and mortality associated with airway management in the ICU. To reduce the likelihood of complications, medical teams must be well versed in the general principles of intubation and be prepared to manage physiologic derangements while securing the airway. In this review, we present relevant literature on the approach to endotracheal intubation in the ICU and provide pragmatic recommendations relevant to medical teams performing intubations in patients who are physiologically unstable.

Preoperative initiation of peripheral veno-arterial extracorporeal membrane oxygenation for a complex case of cardiac tamponade

In this case report, we present an alternative approach to the anaesthetic management of patients presenting with delayed postoperative cardiac tamponade physiology. Given that pericardiocentesis was deemed unsafe, and a protracted surgical dissection was anticipated, peripheral veno-arterial extracorporeal membrane oxygenation (VA-ECMO) support was established prior to induction of anaesthesia to prevent catastrophic circulatory failure. To the best of our knowledge, this is the first reported case of planned preoperative commencement of peripheral VA-ECMO in a complex case of cardiac tamponade. We discuss the challenges associated with this case and the process for selecting this strategy. We also describe the role of transoesophageal echocardiography in planning the surgical approach. This report is completed by a discussion on the topic of delayed postoperative pericardial effusion and tamponade.

Can remimazolam be safely used in cardiac tamponade?: A case report

RATIONALE

Remimazolam, a benzodiazepine drug, has recently been developed and is currently used for the induction and maintenance of anesthesia. Remimazolam provides hemodynamic stability during anesthesia induction. However, in patients with cardiac tamponade, it is unclear how hemodynamic stability is maintained during the induction and maintenance of general anesthesia with remimazolam.

PATIENT CONCERNS

An 88-year-old male patient had developed hemopericardium due to penetration of a pigtail catheter into the left ventricle during pericardiocentesis, which was performed to treat massive pericardial effusion.

DIAGNOSES

The patient was diagnosed with acute cardiac tamponade and a hemothorax. Hemopericardium and hemothorax were confirmed on chest radiography and computed tomography performed immediately after pericardiocentesis.

INTERVENTIONS

Decompressive pericardiostomy was performed through a left anterolateral thoracotomy with 1-lung ventilation under general anesthesia. Remimazolam was administered for total intravenous anesthesia.

OUTCOMES

Severe hypotension and bradycardia occurred during the induction of anesthesia with remimazolam (6 mg/kg/hours).

LESSONS

Remimazolam may induce severe hemodynamic instability during induction of general anesthesia in patient with cardiac tamponade.

Cardiac tamponade

Cardiac tamponade is a medical emergency caused by the progressive accumulation of pericardial fluid (effusion), blood, pus or air in the pericardium, compressing the heart chambers and leading to haemodynamic compromise, circulatory shock, cardiac arrest and death. Pericardial diseases of any aetiology as well as complications of interventional and surgical procedures or chest trauma can cause cardiac tamponade. Tamponade can be precipitated in patients with pericardial effusion by dehydration or exposure to certain medications, particularly vasodilators or intravenous diuretics. Key clinical findings in patients with cardiac tamponade are hypotension, increased jugular venous pressure and distant heart sounds (Beck triad). Dyspnoea can progress to orthopnoea (with no rales on lung auscultation) accompanied by weakness, fatigue, tachycardia and oliguria. In tamponade caused by acute pericarditis, the patient can experience fever and typical chest pain increasing on inspiration and radiating to the trapezius ridge. Generally, cardiac tamponade is a clinical diagnosis that can be confirmed using various imaging modalities, principally echocardiography. Cardiac tamponade is preferably resolved by echocardiography-guided pericardiocentesis. In patients who have recently undergone cardiac surgery and in those with neoplastic infiltration, effusive-constrictive pericarditis, or loculated effusions, fluoroscopic guidance can increase the feasibility and safety of the procedure. Surgical management is indicated in patients with aortic dissection, chest trauma, bleeding or purulent infection that cannot be controlled percutaneously. After pericardiocentesis or pericardiotomy, NSAIDs and colchicine can be considered to prevent recurrence and effusive-constrictive pericarditis.

Anesthetic Considerations for Cardiac Tamponade after Internal Jugular Central Line Placement during Trauma Resuscitation: A Case Report

Numerous complications are associated with central venous catheters. Among them, cardiac tamponade is a rare but well-documented catastrophic complication. A 22-year-old healthy male presented with Code 1 trauma resulting from gunshot wounds in the abdomen. Upon examination, he was found to have a large pericardial fluid collection, a large right supraclavicular hematoma, and significant amount of bilateral pleural effusions secondary to extraluminal placement of the right internal jugular central line during resuscitation. After repairing the internal jugular injury and draining the pericardial fluid, the patient was transferred from the intensive care unit to the regular hospital floor. However, 15 days later, imaging revealed re-accumulation of a large pericardial effusion, which was eventually treated with a pericardial window operation. This case report explores potential complications that could arise from central line placement and the anesthetic considerations in a patient with cardiac tamponade from extraluminal central line placement.

Comprehensive Management of the Patient With Traumatic Cardiac Injury

Cardiac injuries are rare but potentially life-threatening, with a significant proportion of victims dying before arrival at the hospital. The in-hospital mortality among patients who arrive in-hospital alive also remains significantly high, despite major advancements in trauma care including the continuous updating of the Advanced Trauma Life Support (ATLS) program. Stab and gunshot wounds due to assault or self-inflicted injuries are the common causes of penetrating cardiac injuries, while motor vehicular accidents and fall from height are attributable causes of blunt cardiac injury. Rapid transport of victim to trauma care facility, prompt recognition of cardiac trauma by clinical evaluation and focused assessment with sonography for trauma (FAST) examination, quick decision-making to perform emergency department thoracotomy, and/or shifting the patient expeditiously to the operating room for operative intervention with ongoing resuscitation are the key components for a successful outcome in cardiac injury victims with cardiac tamponade or exsanguinating hemorrhage. Blunt cardiac injury with arrhythmias, myocardial dysfunction, or cardiac failure may need continuous cardiac monitoring or anesthetic care for operative procedure of other associated injuries. This mandates a multidisciplinary approach working in concert with agreed local protocols and shared goals. An anesthesiologist has a pivotal role to play as a team leader or member in the trauma pathway of severely injured patients. They are not only involved in in-hospital care as a perioperative physician but also participate in the organizational aspects of prehospital trauma systems and training of prehospital care providers/paramedics. There is sparse literature available on the anesthetic management of cardiac injury (penetrating as well as blunt) patients. This narrative review discusses the comprehensive management of cardiac injury patients, focusing on the anesthetic concerns and is guided by our experience in managing cardiac injury cases at Jai Prakash Narayan Apex Trauma Center (JPNATC), All India Institute of Medical Sciences, New Delhi. JPNATC is the only level 1 trauma center in north India, providing services to a population of approximately 30 million with around 9000 operations being performed annually.

Advanced diagnostic and therapeutic techniques for anaesthetists in thoracic trauma: an evidence-based review

Anaesthetists play an important role in the evaluation and treatment of patients with signs of thoracic trauma. Anaesthesia involvement can provide valuable input using both advanced diagnostic and therapeutic interventions. Commonly performed interventions may be complicated in this setting including airway management, damage control resuscitation, and acute pain management. Anaesthetists must consider additional factors including airway injuries, vascular injuries, and coagulopathy when treating this population. This evidence-based review discusses traumatic thoracic injuries with a focus on new interventions and modern anaesthesia techniques. This review further serves to support the early involvement of anaesthetists in the emergency department and other areas where they can provide value to the trauma care pathway.

Pericardiectomy and Pericardial Window for the Treatment of Pericardial Disease in the Contemporary Era

PURPOSE OF REVIEW

To summarize the contemporary practice of pericardiectomy and pericardial window. We discuss the indications, preoperative planning, procedural aspects, postprocedural management, and outcomes of each procedure.

RECENT FINDINGS

Surgical approaches for the treatment of pericardial disease have been around even before the emergence of cardiopulmonary bypass. Since the forthcoming of cardiopulmonary bypass, there have been significant changes in the epidemiology and diagnostic approach of pericardial diseases as well as advancements in the surgical techniques and perioperative management used in the care of these patients. Pericardiectomy has an average mortality of almost 7% and is typically performed in patients with advanced symptoms from constrictive pericarditis and relatively few comorbidities. Pericardial window is a safe procedure for the treatment of pericardial effusion that can be performed with different approaches.
