[Clonidine as adjuvant therapy for alcohol withdrawal syndrome in intensive care unit: case report.].
Sedation of patients with past history of alcohol and drug abuse in Intensive Care Units (ICU) is a challenge due to the high incidence of sedative drugs tolerance and withdrawal syndromes. This report aimed at describing a case of a young patient admitted to the ICU who developed alcohol withdrawal syndrome and tolerance to sedatives, resolved only after clonidine administration. ⋯ Benzodiazepines should remain the drugs of choice for the treatment of acute alcohol withdrawal syndrome. However in this report, only adjuvant clonidine was able to adequately treat the patient.

[Effects of tracheal tube cuff limit pressure (25 cmH2O) and "seal" pressure on tracheal mucosa of dogs.].
Injuries of tracheal mucosa in contact with tracheal tube cuff is a function of cuff pressure and exposure time. This study aimed at analyzing injuries of tracheal mucosa in contact with tracheal tube cuff inflated to reach "seal" pressure or limit 25 cmH2O pressure, below critical 30 cmH2O, to prevent tracheal damage. ⋯ In dogs under our experimental conditions, tracheal tube cuff inflation to 25 cmH2O limit or to "seal" pressure to prevent air leakage has determined minor injuries to the tracheal mucosa in contact with tracheal tube cuff, without significant differences between groups.

[Hemodynamic changes during pneumoperitoneum in volume and pressure controlled ventilated dogs.].
There are no studies associating ventilation-induced effects and hemodynamic changes during pneumoperitoneum. This study aimed at evaluating hemodynamic changes determined by pneumoperitoneum in dogs under volume and pressure controlled ventilation. ⋯ Ventilation modes have not determined hemodynamic differences between studied groups. Anesthetic technique and intra-abdominal pressure have determined mean blood pressure stability, probably due to the absence of systemic vascular resistance index increase.

[Post-cesarean section analgesia with low spinal morphine doses and systemic nonsteroidal anti-inflammatory drug: diclofenac versus ketoprofen.].
The association of low spinal morphine doses and muscular diclofenac is effective to control postoperative pain after Cesarean section under spinal anesthesia. Ketoprofen, also an NSAID, may be advantageous over diclofenac because it may be intravenously administered. This study aimed at comparing the analgesic efficacy of diclofenac and ketoprofen in association to low spinal morphine doses in the immediate postoperative period of patients submitted to Cesarean section under spinal anesthesia. ⋯ When associated to low spinal morphine doses, ketoprofen was similar to diclofenac in providing postoperative analgesia in the first six hours following Cesarean section under spinal anesthesia.

Scleroderma or progressive systemic sclerosis is a systemic connective tissue disease of unknown origin, which normally courses with microangiopathy, extremities ischemia and severe pain. This report aimed at describing a case of intravenous lidocaine to treat ischemic pain and at emphasizing potential anti-inflammatory action of local anesthetics in scleroderma patients. ⋯ Pain and other symptoms relief after intravenous lidocaine suggests that local anesthetics are able to modulate inflammatory response in different scleroderma stages.
