OBJECTIVE: Cardiac arrhythmias are a common challenge following open-heart surgeries. Hypomagnesemia is believed to be correlated with this condition. Prophylactic intravenous magnesium supplementation has been practiced for a long time in patients undergoing CABG. This study was designed in an attempt to compare the efficacy of oral versus intravenous routes in the prevention of hypomagnesemia and arrhythmia. METHODS: In this interventional clinical study, 82 patients were randomly assigned to 2 groups...

RATIONALE: Cardiac inflammatory myofibroblastic tumor (IMT) is a rare primary cardiac tumor which is currently considered as a low-grade neoplasm. The tumor has a predilection in infants and adolescents and primarily occurs as an endocardial-based cavitary mass. However, cardiac IMT that only involves the interventricular septum in middle-aged adults is extremely rarely reported. Considering its infrequency, we report a rare clinical case, with the aim of sharing our experience during the diagnostic procedures...

Pentalogy of Cantrell is a congenital anomaly associated with defects in the abdominal wall, sternum, diaphragm, and diaphragmatic pericardium formation, in addition to the development of cardiac abnormalities. It is a rare disease with an estimated incidence of one case for every 65,000 births, being more common in males (60% of cases). It has a reserved prognosis with mortality around 63%, and a maximum of 9 months survival after surgery. There are few case reports addressing the pentalogy of Cantrell, which is justified by the rarity of this pathology...

Background: Intravascular air embolism (AE) is a preventable but potentially catastrophic complication caused by intravenous tubing, trauma, and diagnostic and surgical procedures. The potentially fatal risks of arterial AE are well-known, and emerging evidence demonstrates impact of venous AEs on inflammatory response and coagulation factors. A novel FDA-approved in-line air detection and purging system was used to detect and remove air caused by administering a rapid fluid bolus during surgery...

The report describes a case of peri-operative stroke that presented as diplopia and gait difficulty on 2nd post-operative day after routine orchidopexy under spinal anesthesia in an otherwise healthy young boy. Magnetic resonance imaging of the brain revealed acute infarct in bilateral cerebellar hemispheres, left half of medulla and left thalamus. A diagnosis of acute stroke (infarct) was made and patient was started on oral aspirin , following which his vision started improving after 2 weeks. Possible mechanisms of development of stroke in the peri-operative period are discussed, but, even after extensive investigations, the etiology of infarct may be difficult to determine...

Baroreflex sensitivity (BRS) can be noninvasively assessed from heart period (HP) and arterial pressure (AP) variability series via the estimation of the gain of the transfer function (TF) in the low frequency (LF, 0.04-0.15 Hz) band. However, different strategies can be adopted to pick the value of the TF gain and different fiducial AP values can be considered. In this study we compared different strategies to reduce the TF gain into a unique maker: i) sampling the TF gain in correspondence of the maximum of the HP-AP squared coherence; ii) sampling the TF gain at the weighted average of the central frequencies of AP spectral components; iii) calculating the average of the TF gain in the LF band...

Atrial fibrillation (AF) is the most common type of cardiac arrhythmia. Although not life-threatening itself, AF significantly increases the risk of stroke and myocardial infarction. Current tools available for screening and monitoring of AF are inadequate and an unobtrusive alternative, suitable for long-term use, is needed. This paper evaluates an atrial fibrillation detection algorithm based on wrist photoplethysmographic (PPG) signals. 29 patients recovering from surgery in the post-anesthesia care unit were monitored...

Four thousand cardiac implantable electronic devices (CIED) are implanted yearly in Croatia with constant increase. General anesthesia and surgery carry some specific risk for the patients with implanted CIEDs. Since most of the surgical procedures are performed in institutions without reprogramming devices available, or in the periods when they are unavailable, these guidelines aim to standardize the protocol for perioperative management of these patients. With this protocol, most of the procedures can be performed easily and, more importantly, safely in the majority of surgical patients...

BACKGROUND: Both selective digestive decontamination (SDD) and probiotics have been reported to reduce endotoxemia. However, the available results are conflicting and few studies have investigated the combined effect of SDD and probiotics. This study aimed to examine the effectiveness of a comprehensive preoperative regimen of SDD in combination with probiotics and smectite on perioperative endotoxemia and cytokine activation in patients who underwent elective cardiac surgery with cardiopulmonary bypass (CPB) in a pilot, prospective, randomized, controlled trial...

BACKGROUND: Prone positioning (PP) is necessary for surgical access during posterior spine procedure. However, physiological changes occur in the PP. Typical findings are a decrease in arterial blood pressure and in cardiac output that could potentially lead to an alteration in cerebral perfusion. Therefore, we decided to study cerebral blood flow velocity (CBFV) with transcranial Doppler ultrasonography to evaluate the effect of the PP on cerebral hemodynamics. METHODS: Twenty-two patients undergoing spine surgery in the PP were studied...

Anesthesia-Induced Hypothermia (AIH) has been reported to be the cause of many postoperative adverse effects, including increased mortality, decreased immune responses, cardiac events, and a greater prevalence of postoperative surgical wound infections. AIH can in some cases be minimized with pre-warming fluids and gases and forced-air heating systems, but such techniques are not always effective and can result in patient burns or other adverse effects. Stimulation of 5-HT2 receptors has been reported to increase body temperature through a variety of mechanisms, and as such, may be a viable target for pharmacologically minimizing AIH...

Myocardial ischemic events after non-cardiac surgery is still a serious problem, especially in older, high-risk patients. However, the prevalence and risk factors of blood pressure (BP) abnormalities, which may possibly lead to myocardial ischemic attack, have not been reported. Our aim is to elucidate predictive factors of postoperative BP abnormalities following a minor-to-moderate surgery, employing preoperative left ventricular diastolic function. Patients who underwent cardiac echocardiogram examination and received oral and maxillofacial surgery under general anesthesia were enrolled...

BACKGROUND: Perioperative complications occur in 30-40% of non-cardiac surgical patients and are the leading cause of early postoperative morbidity and mortality. Regular visits by trained health professionals may decrease the incidence of complications and mortality through earlier detection and adequate treatment of complications. Until now, no studies have been performed on the impact of routine postsurgical anesthesia visits on the incidence of postoperative complications and mortality...

BACKGROUND: Cardiac surgery with cardiopulmonary bypass (CPB) is associated with acute kidney injury, and the risk increases with low oxygen delivery during CPB. We hypothesized that renal oxygenation could be improved at higher than normal CPB flow rates. METHODS: After ethical approval and informed consent, 17 patients with normal serum creatinine undergoing normothermic CPB were included and received pulmonary artery and renal vein catheters after anesthesia induction for measurements of systemic and renal variables...

BACKGROUND: Preoperative factors have been correlated with pre-incision hypotension (PIH) in children undergoing surgery, suggesting that PIH can be predicted through preoperative screening. We studied blood pressure (BP) changes in the 12 min following the induction of anesthesia to study the incidence of post-induction hypotension and to assess the feasibility of predicting PIH in low-risk children without preoperative hypotension or comorbid features. METHODS: We retrospectively evaluated 200 patients ranging in age from 2 to 8 years with American Society of Anesthesiologists' (ASA) physical status I or II, undergoing non-cardiac surgery...

Cardiac arrest in the operating room is a life-threatening event with multiple causes. We report the case of a 53-year old female patient with no particular past medical history scheduled for surgery to manage small intestine cancer. Twenty minutes after anesthetic induction the patient had asystole rapidly reversible after resuscitation measures. The association of face rash with chest rash gave rise to suspicion of late anaphylactic reaction. Rapid patient recovery allowed to resume surgical procedure. Tumor manipulation immediately caused a second severe bradycardia rapidly reversible after the administration of 0...
