ABSTRACT

AIM: To investigate whether the fluid volume administered during esophageal cancer surgery affects pulmonary gas exchange and tissue perfusion. METHODS: An exploratory single-center randomized clinical trial was performed. Patients with esophageal cancer who underwent Lewis-Tanner procedure between June 2011 and August 2012 at the Department of Thoracic surgery "Jordanovac", Zagreb were analyzed. Patients were randomized (1:1) to receive a restrictive volume of intraoperative fluid (≤8 mL/kg/h) or a liberal volume (>8 mL/kg/h). Changes in oxygen partial pressure (Pao2), inspired oxygen fraction (FiO2), creatinine, and lactate were measured during and after surgery. RESULTS: Overall 16 patients were randomized and they all were analyzed (restrictive group n=8, liberal group n=8). The baseline value Pao2/FiO2 ratio (restrictive) was 345.01±35.31 and the value six hours after extubation was 315.51±32.91; the baseline Pao2/FiO2 ratio (liberal) was 330.11±34.71 and the value six hours after extubation was 307.11±30.31. The baseline creatinine value (restrictive) was 91.91±12.67 and the value six hours after extubation was 100.88±18.33; the baseline creatinine value (liberal) was 90.88±14.99 and the value six hours after extubation was 93.51±16.37. The baseline lactate value (restrictive) was 3.93±1.33 and the value six hours after extubation was 2.69±0.91. The baseline lactate value (liberal) was 3.26±1.25 and the value six hours after extubation was 2.40±1.08. The two groups showed no significant differences in Pao2/FiO2 ratio (P=0.410), creatinine (P=0.410), or lactate (P=0.574). CONCLUSIONS: Restriction of intraoperative applied volume does not significantly affect pulmonary exchange function or tissue perfusion in patients undergoing surgical treatment for esophageal cancer.

ABSTRACT

SUMMARY - Post-intubation tracheal injury is a rare and potentially fatal complication. The most common causes are overinflation ofendotracheal tube cuffs and multiple intubation attempts in emergency cases. The diagnosis is based on clinical and radiological suspicion of tracheal injury confirmed by fiberoptic bronchoscopy. Decision between conservative and surgical management of the injury depends on clinical presentation (respiratory instability, concomitant diseases), lesion characteristics (lesion site, size, and number), and time elapsed from injury to diagnosis. We present three cases ofpost-intubation tracheal injury. In two cases, the patients were treated conservatively; in the third case, the patient died from asphyxia caused by thrombus occlusion of the trachea after a longitudinal tracheal lesion. Pre-anesthetic examination did not indicate any possibility of difficult intubation in any of the patients; however, in one of the patients admitted through the emergency department, emergency intubation was performed.

ABSTRACT

Magnesium can act as an adjuvant in analgesia due to its properties of calcium channel blocker and N-methyl-D-aspartate antagonist. The aim of our study was to determine if magnesium sulfate reduces perioperative analgesic requirements in patients undergoing thoracotomy procedure. Our study included 68 patients undergoing elective thoracotomy that received a bolus of 30-50 mg/kg MgSO4 followed by continuous infusion of 500 mg/h intraoperatively and 500 mg/h during the first 24 hours after the operation, or the same volume of isotonic solution (control group). Intraoperative analgesia was achieved with fentanyl and postoperative analgesia with a mixture of fentanyl and bupivacaine through epidural catheter. The level of pain was estimated using Visual Analog Scale (VAS) and TORDA pain scales. Fentanyl consumption during the operation was significantly lower in the magnesium treated group compared to control group. There was no statistically significant difference in epidural bupivacaine and fentanyl consumption during 48 hours postoperatively between the magnesium treated and control group. The measured VAS score at all intervals was similar in both groups. Postoperative TORDA scores were similar in both groups during the first 24 hours; however, a statistically significant difference was recorded in 40-48 h measurements. Results of our study revealed that magnesium reduced intraoperative analgesic requirements and also contributed to effective control of the static component of postthoracotomy pain.

ABSTRACT

A 70-year old female patient was admitted to the hospital because of scheduled thoracotomy and biopsy of posterior mediastinal retrocardiac tumor of unrecognized etiology. The patient had no complaints regarding the tumor. Routine anesthesiological preoperative examination revealed status ASA III. Induction in anesthesia was usually stable. At the moment when the surgeon intraoperatively touched the tumor, hemodinamic instability started and arterial blood pressure and heart rate dramatically increased. Our first reaction was to deepen the anesthesia. Very soon it was obvious that blood pressure increased by the surgeon's manipulation of the tumor and we started to doubt on catecholamine-secreting tumor. During the course of the operation there were several hypertensive episodes and we managed them by alternately using atenolol, glyceroltrinitrate and anesthetic drug. The patient was extubated 5 hours after transfer to the intensive care unit. Postoperative period was hemodynamically stable. The level of catecholamines in 24-hour urine collection was significantly increased. Pathohistologic diagnosis was mediastinal paraganglioma.

ABSTRACT

BACKGROUND AND OBJECTIVE: It is not precisely defined which group of non-cardiac surgery patients should undergo transthoracic echocardiography in preoperative preparation. This study was prospectively performed to find out whether the routine use of echocardiography is justified in patients scheduled for lung resection, and to assess its role in cardiac risk evaluation. METHODS: Patients classified as ASA III who were identified as having minor or intermediate predictors of cardiac risk were included in the study. Based on this triage, 130 patients underwent transthoracic echocardiography. RESULTS: Intermediate index of increased perioperative cardiovascular risk was recorded in 36.2% and low index in 63.8% of patients. Preoperative anesthesiologic examination revealed some form of cardiac arrhythmia in 28.5%, symptoms of coronary disease in 25.4%; hypertension in 52.3%, and chronic obstructive pulmonary disease in 16.9% of patients. Transthoracic echocardiography showed the ejection fraction of 60% in 86.9% and of 40%-49% in only one patient. Left ventricular contractility was preserved in 96.2% of patients. Diastolic relaxation was weakened in 42.3% of patients. Mild mitral insufficiency was found in 29.2%; aortic stenosis in 1.5%, mild aortic insufficiency in 2.3%, mild pulmonary hypertension in 70.8%, and severe pulmonary hypertension in only 1.5% of patients. Pulmonectomy was performed in 26.9%, lobectomy in 62.3% and segmental tumor resection in 10.8% of patients. Only 26.2% of patients had peri- and postoperative complications: tachyarrhythmia and atrial fibrillation with rapid ventricular answer in 16.2%, hypotension 1.5%; hypertension in 2.3% and hypertension and arrhythmia in 1.5% of patients. Three (2.3%) patients died. None of our patients had Goldman's score higher than 25; according to Detsky index our patients belonged to 0-15 point group, class I, with the foreseen risk %. CONCLUSIONS: Transthoracic echocardiography is not justified in the routine preoperative preparation of thoracosurgical patients classified as ASA III with clinically minor and intermediate indexes of increased cardiovascular risk. It should be done in selected patients, primarily those that have history data and clinical picture consistent with major indices of an increased cardiovascular risk.
