PURPOSE OF REVIEW: The purpose of this review is to identify chronic pulmonary conditions which may often not be recognized preoperatively especially before elective noncardiac surgery and which carry the highest risk of perioperative morbidity and mortality. RECENT FINDINGS: This review discusses some of the most recent studies that highlight the perioperative complications, and their prevention and management strategies. SUMMARY: Pulmonary hypertension is a well recognized risk factor for postoperative complications after cardiac surgery but the literature surrounding noncardiac surgery is sparse...

REVIEW
Geraldine C Diaz, Michael F O'Connor, John F Renz
Hepatic function and pulmonary function are interrelated with failure of one organ system affecting the other. With improved therapies, patients with concomitant hepatic and pulmonary failure increasingly enjoy a good quality of life and life expectancy. Therefore, the prevalence of such patients is increasing with more presenting for both emergent and elective surgical procedures. Hypoxemia requires a thorough evaluation in patients with end-stage liver disease. The most common etiologies respond to appropriate therapy...

Competitive flows syndrome result in severe regional hypoxemia when the deoxygenated flow from the native left ventricle (LV) competes with oxygenated flow from extracorporeal life support (ECLS) pump with potentially severe consequences for the cerebral and coronary circulations. Fast correction of hypoxemia could be obtained by decreasing native LV flow by infusion of a short-acting beta-blocker (esmolol). Our purpose was to retrospectively review the efficacy of esmolol in this situation and hypothesize on the potential mechanisms of action and the associated risks...

BACKGROUND: Non-invasive high-resolution echocardiography to evaluate cardiovascular function of small animals is increasingly being used due to availability of genetically engineered murine models. Even though guidelines and standard values for humans were revised by the American Society of Echocardiography, evaluations on murine models are not performed according to any standard protocols. These limitations are preventing translation of preclinical evaluations to clinical meaningful conclusions...

Patent ductus arteriosus (PDA) is an extracardiac left to right shunt. It should be corrected at an early age, but some patients may survive into adult life even without repair. Anesthetic management for adult patients with PDA poses many challenges for the anesthesiologist due to alterations in the cardiopulmonary physiology. We report successful anesthesia management of a case of an adult patient of PDA with moderate pulmonary artery hypertension with infective endarteritis (two large mobile vegetations at the pulmonary end of the duct)...

BACKGROUND: In patients with severe pulmonary arterial hypertension, subcutaneous or catheter-based intravenous application of prostanoids carries a risk of local side effects or systemic infections, which limits their use and acceptance. Recently, a fully implantable pump for continuous application of intravenous treprostinil was approved in Germany. However, surgery is a major risk for patients with severe pulmonary arterial hypertension. The purpose of this study was to investigate the safety of a fully implantable pump inserted under local or general anesthesia in patients with severe pulmonary hypertension...

Hypoxic pulmonary vasoconstriction (HPV) is a homeostatic mechanism that is intrinsic to the pulmonary vasculature. Intrapulmonary arteries constrict in response to alveolar hypoxia, diverting blood to better-oxygenated lung segments, thereby optimizing ventilation-perfusion matching and systemic oxygen delivery. In response to alveolar hypoxia, a mitochondrial sensor dynamically changes reactive oxygen species and redox couples in PASMC. This inhibits potassium channels, depolarizes PASMC, activates voltage-gated calcium channels, and increases cytosolic calcium, causing vasoconstriction...

BACKGROUND: Mucopolysaccharidosis (MPS) IVA is a rare lysosomal storage disorder with multiple skeletal and non-skeletal abnormalities requiring multiple surgical interventions. It is well known that patients with MPS IVA suffer from tachycardia, but cardiac and hemodynamic alterations have not been reported to date. We investigated the cardiovascular and hemodynamic alterations in patients with MPS IVA and developed a possible patho-mechanism for cardiovascular deterioration during anesthesia...

The maternal mortality rate for parturients with severe pulmonary hypertension is 30% to 50%. General, epidural, and combined low-dose spinal-epidural anesthesia have been used successfully for cesarean deliveries in patients with pulmonary hypertension. We describe a cesarean delivery performed using an intrathecal catheter in a 25-year-old morbidly obese (body mass index, 82 kg/m) woman (gravida 3, para 2 at 32 weeks of gestation) who had severe pulmonary hypertension, right ventricular failure, pulmonary emboli, and obstructive sleep apnea...

Recent studies suggest right ventricular (RV) stiffness is important in pulmonary hypertension (PH) prognosis. Smaller stroke volume (SV) variation after a certain RV end-diastolic pressure (EDP) respiratory variation as assessed by spectral transfer function (STF) may identify RV stiffness. Our aim was to evaluate RV stiffness in monocrotaline (MCT)-induced PH progression and to validate STF gain between EDP and SV as marker of stiffness. Seven-week-old male Wistar rats randomly injected with 60 mg/kg MCT or vehicle were divided into three groups (n = 12 each) according to cardiac index (CI): controls (Ctrl), preserved CI (MCT pCI), and reduced CI (MCT rCI)...

PURPOSE: Inhaled milrinone (iMil) has been used for the treatment of pulmonary hypertension (PH) but its efficacy, safety, and prophylactic effects in facilitating separation from cardiopulmonary bypass (CPB) and preventing right ventricular (RV) dysfunction have not yet been evaluated in a clinical trial. The purpose of this study was to investigate if iMil administered before CPB would be superior to placebo in facilitating separation from CPB. METHODS: High-risk cardiac surgical patients with PH were randomized to receive iMil or placebo after the induction of anesthesia and before CPB...

Rheumatic heart disease is the most common cardiac disease complicating pregnancy in developing countries. Heart disease accounts for 15% pregnancy-related mortality. In the presence of maternal heart disease, the circulatory changes of pregnancy may result in exacerbation of the hemodynamic perturbations due to complex cardiac valvular lesions leading to decompensation or death of mother or fetus. Determining the ideal anesthetic technique for cesarean section in the presence of complex cardiac conditions remains a much debated topic...

Severe pulmonary arterial hypertension is a significant risk factor for anesthetic management in patients undergoing even non-cardiac surgery. A 64-year-old female patient with severe pulmonary arterial hypertension was scheduled to undergo inguinal hernioplasty. Preoperative systolic pulmonary arterial pressure was 115 mmHg. We selected monitored anesthesia care with 0.2-0.5 μg x kg(-1) x hr(-1) dexmedetomidine and ultrasound-guided iliohypogastric block. Thereafter, LiDCOrapid was used to acquire the hemodynamic responses during surgery...

A 32-year-old man with severe pulmonary arterial hypertension and Eisenmenger syndrome secondary to congenital ventricular septal defects presented for ventriculoperitoneal shunt insertion. Consultation between surgical and anesthesia teams acknowledged the extreme risk of performing this case, but given ongoing symptoms related to increased intracranial pressure from a large third ventricle colloid cyst, the case was deemed urgent. After a full discussion with the patient, including an explanation of anesthetic expectations and perioperative risks, the case was performed under monitored anesthesia care...

BACKGROUND: Idiopathic pulmonary arterial hypertension (IPAH) is a progressive and fatal cardiovascular disease if left untreated. In patients with IPAH with psychiatric illness or other complications, careful attention is required when administering medical therapies that may affect their hemodynamics. Patients suffering from IPAH who undergo anesthesia and surgery have a high mortality and morbidity rate. We describe the treatment of intractable psychiatric symptoms with electroconvulsive therapy (ECT) in a patient with IPAH...

Pulmonary arterial hypertension (PAH) is a known risk factor of perioperative complications, but the risks for non-cardiac operations have not yet been examined sufficiently. We report a case of a right lower lobectomy in a patient with PAH. A 73-year-old woman with Sjögren's syndrome was scheduled for right lowr lobectomy for primary lung cancer under general anesthesia. She was diagnosed with symptomatic PAH (estimated mean pulmonary arterial pressure, 40 mmHg) and medicated with ambrisentan. After induction of general anesthesia with propofol and fentanyl, a pulmonary artery catheter was placed to measure pulmonary artery pressure...
