Randomized Controlled Trial Comparative Study Clinical TrialImproved long-lasting postoperative analgesia, recovery function and patient satisfaction after inguinal hernia repair with inguinal field block compared with general anesthesia.
Inguinal hernia repair is a common surgical procedure, and different types of anesthetic techniques are in use. We wanted to test if preoperative inguinal field block (IFB) with ropivacaine would provide benefits in the postoperative period compared with general anesthesia and wound infiltration. ⋯ Preoperative inguinal field block for hernia repair provides benefits for patients in terms of faster recovery, less pain, better mobilization and higher satisfaction throughout the whole first postoperative week.

Clinical TrialPlasma cholinesterase activity and duration of action of mivacurium in phenotypically normal patients.
The short duration of action of mivacurium is due to its rapid hydrolysis by plasma cholinesterase (pChe). In patients with normal phenotype, low pChe activity because of, for instance, disease or intake of drugs may prolong the duration of action of mivacurium. The purpose of this study was to evaluate the relationship between pChe activity and the duration of action of mivacurium 0.2 mg/kg in phenotypically normal patients. ⋯ In patients with phenotypically normal pChe, prediction of the duration of action of mivacurium is possible from the patients actual pChe activity. In patients with pChe activities below the normal range, the time to reappearance of the first response to TOF stimulation may vary from 10 to 180 min Only patients with pChe activities <220 U/l had a significantly prolonged duration of action of mivacurium.

Case ReportsAnterior ischemic optic neuropathy after emergency caesarean section under epidural anesthesia.
We report a case of non arteritic anterior ischemic optic neuropathy following caesarean delivery in a patient who had epidural analgesia. There was doubt as to whether it was subdural. The patient underwent caesarean section because of second stage non-progression of labor. We discuss the possible etiology of this unpleasant complication.

Intensive care unit syndrome/delirium is associated with anemia, drug therapy and duration of ventilation treatment.
We have performed a prospective qualitative investigation of the ICU syndrome/delirium; the main parts of which have recently been published. The aim of the present study was to explore the relationship between the ICU syndrome/delirium and age, gender, length of ventilator treatment, length of stay and severity of disease, as well as factors related to arterial oxygenation and the amount of drugs used for sedation/analgesia. ⋯ The development of the ICU syndrome/delirium seems to be associated with decreased hemoglobin concentrations and extended times on the ventilator. Prolonged ICU stays and treatment with higher doses of sedatives and opioids in patients with delirium appear to be secondary phenomena rather than causes.

Comparative StudyComparative effects of xenon and nitrous oxide on diaphragmatic contractility in dogs.
Xenon at two different concentrations (30%, 60%) has no effect on diaphragmatic contractility. This study was undertaken to compare the effects of xenon and nitrous oxide (N2O), a commonly used and well-established gas anesthetic, on diaphragmatic contractility in dogs. ⋯ When used at clinical concentration, xenon or N2O does not affect contractility and electrical activity of the diaphragm in dogs.
