Randomized Controlled Trial Clinical TrialThe effect of acute normovolemic hemodilution on homologous blood requirements and total estimated red blood cell volume lost.
Acute normovolemic hemodilution combined with retransfusion is one of the various techniques proposed to avoid homologous blood transfusion in cardiac surgery. The purpose of the present paper is to study the effect of the volume of autologous blood collected pre-cardiopulmonary bypass (CPB) on homologous blood requirements and total estimated red blood cell (RBC) volume lost in coronary artery bypass grafting (CABG) surgery. ⋯ Acute intraoperative hemodilution with high- and low-volume phlebotomy reduced the homologous blood requirements similarly regardless of the amount of phlebotomy.

Case ReportsLarge increase in cardiac output in a patient with ARDS and acute right heart failure during inhalation of nitric oxide.
Inhaled nitric oxide (NO), a selective pulmonary vasodilator, reduces pulmonary artery pressure in patients with acute respiratory distress syndrome (ARDS). In spite of the reduction of right ventricular afterload, the effect of NO on cardiac output remains unclear. ⋯ Our observations suggest that inhalation of NO is likely to increase cardiac output in ARDS when severe acute right heart failure is present.

Case ReportsIntraoperative epidural catheter malfunction in two obese patients.
Using a combined general anesthesia/epidural technique, two cases of intraoperative malfunctioning epidural catheters in obese patients are presented. After the epidural was found to be malfunctioning, the anesthesiologist placed the palm of both hands underneath the patients' lumbar and thoracic area. ⋯ In each case, this simple maneuver made the catheter function again. In conclusion, this simple corrective maneuver should be attempted prior to discarding the epidural anesthetic technique.

Postoperative analgesia in Italy. National survey on the anaesthetist's beliefs, opinions, behaviour and techniques in postoperative pain control in Italy.
Using a personal, anonymous questionnaire developed ad hoc, we tried to document the role, the problems and the activities of Italian anaesthetists in postoperative pain control. ⋯ This survey shows that Italian anaesthetists do not consider the postoperative period to be their own personal work area and that POA is to be considered as a matter of individual choice.
