The sublingual microcirculation is globally unaltered by red blood cell transfusion in septic patients; however, it can improve in patients with altered capillary perfusion at baseline.

IPV treatment was feasible for all patients. Noninvasive positive-pressure ventilation by helmet associated with IPV reduces the duration of ventilatory treatment and intensive care unit stay and improves gas exchange at discharge from intensive care unit in patients with severe exacerbation of COPD.

We investigated the pharmacodynamic effects of rocuronium on morbidly obese patients. Twelve morbidly obese female patients (body mass index >40 kg/m(2)) admitted for laparoscopic gastric banding were randomized into two groups. Group 1 (n = 6) received 0.6 mg/kg of rocuronium based on real body weight, whereas Group 2 (n = 6) received 0.6 mg/kg of rocuronium based on ideal body weight. In a control group of six normal-weight female patients admitted for laparoscopic surgery, rocuronium was dosed on the basis of their real body weight. Neuromuscular transmission was monitored by using acceleromyography of the adductor pollicis; anesthesia was induced and maintained with remifentanil and propofol. The onset time tended to be shorter in Group 1 and the control group compared with Group 2, but this did not achieve statistical significance. Duration of action to 25% of twitch tension was more than double in Group 1 (55 min) compared with the other two groups (22 and 25 min; P < 0.001). Duration of action was similar between Group 2 and control. Recovery index tended to be longer in Group 1, but without a significant difference. In conclusion, in morbidly obese patients, the duration of action of rocuronium is significantly prolonged when it is dosed according to real body weight. Therefore, the dosage should be assessed on the basis of ideal rather than on real body weight in clinical practice.

DAA administration rapidly improves sepsis-induced microvascular alterations, whereas its cessation is associated with a transient deterioration.

When ICP was higher than 20 mm Hg, the ONSD diameter increased, whereas when the ICP was below 20 mm Hg, the ONSD returned to values equivalent to those assessed in control nontrauma patients. Accordingly, ocular ultrasound may be considered as a good alternative for a rapid indirect evaluation of head trauma patients' ICP.
