Randomized Controlled TrialAcetaminophen decreases early post-thoracotomy ipsilateral shoulder pain in patients with thoracic epidural analgesia: a double-blind placebo-controlled study.
Despite effective epidural analgesia, up to 85% of post-thoracotomy patients complain of moderate-to-severe ipsilateral shoulder pain. This study assessed the efficacy of acetaminophen in decreasing postoperative shoulder pain after a thoracotomy. ⋯ Acetaminophen decreases post-thoracotomy ipsilateral shoulder pain when given preemptively and regularly during the first 48 hours postoperatively in patients who received thoracic epidural analgesia.

Comparative StudyMajor clinical outcomes in adults undergoing thoracic aortic surgery requiring deep hypothermic circulatory arrest: quantification of organ-based perioperative outcome and detection of opportunities for perioperative intervention.
The purpose of this study was to describe clinical outcome after adult thoracic aortic surgery requiring standardized deep hypothermic circulatory arrest (DHCA), to determine mortality and length of stay, neurologic outcome, cardiorespiratory outcome, and hemostatic and renal outcome after DHCA. ⋯ The protocol for DHCA at the authors' institution is associated with superior or equivalent perioperative outcomes to those reported in the literature. This study identified the need for further quantification of the clinical outcomes after DHCA in order to prioritize outcome-based hypothesis-driven prospective intervention in DHCA.

Comparative StudyMonitoring oxygenator expiratory isoflurane concentrations and the bispectral index to guide isoflurane requirements during cardiopulmonary bypass.
The purpose of this study was to measure the changes in isoflurane requirements during the rewarming phase of cardiopulmonary bypass with moderate hypothermia. ⋯ Isoflurane requirements are reduced during hypothermic cardiopulmonary bypass. Monitoring anesthetic concentrations in the oxygenator expiratory gas may be a useful adjunct to monitoring the depth of anesthesia.

Comparative StudyClinical experience with polyclonal IgM-enriched immunoglobulins in a group of patients affected by sepsis after cardiac surgery.
The purpose of this study was to evaluate the efficiency, in terms of decreasing overall mortality (primary endpoint), of an immunoglobulin M (IgM)-enriched, polyclonal intravenous immunoglobulin preparation (IVIg) (Pentaglobin; Biotest AG, Dreieich, Germany) in the treatment of a group of patients affected by sepsis after cardiac surgery. A secondary endpoint was to evaluate which subgroup, on the basis of the infectious state when the patient enrolled, could benefit the most from the treatment. Another secondary endpoint was the evaluation of an improvement in the severity score or in other variables such as Glasgow Coma Scale; arterial pressure (systolic, average, and diastolic); heart rate; central venous pressure; cardiac index; respiratory rate; PaO(2), F(I)O(2), and the ratio of PaO(2) to F(I)O(2); pH, base excess, and bicarbonate; C reactive protein and leukocytes; platelets, prothrombin time, partial thromboplastin time, fibrinogen, and anti-thrombin III; creatinine; and bilirubin. ⋯ The polyclonal IgM-enriched immunoglobulins did not significantly reduce the mortality rate in the overall study population. However, in the subgroup of patients with severe sepsis, they improved the survival rate significantly.

Comparative StudyPatterns of changes in arterial PO2 during one-lung ventilation: a comparison between patients with severe pulmonary emphysema and patients with preserved lung function.
One-lung ventilation (OLV) during thoracoscopic surgery is associated with a significant decline in arterial PO(2) in patients with severe pulmonary emphysema and patients with preserved lung function. The authors hypothesized that patterns of arterial PO(2) changes are different in these 2 patient groups. ⋯ During OLV, oxygenation is better preserved for a longer period of time in patients with severe pulmonary emphysema as compared with patients with normal lung function. In contrast to patients without emphysema, prediction of oxygenation during OLV for the individual patient with emphysema is unreliable because of large interindividual differences.
