Filter by:Caudal injection of local anesthetic is a neuraxial technique routinely performed on young children for postoperative analgesia after lower abdominal and lower extremity surgical procedures. One of the major limitations of the use of single shot neuraxial injections for this purpose is the limited duration of action of the injected local anesthetic. Adjuvant medications, such as clonidine and epinephrine, have been added to the local anesthetic to prolong the duration of the neuraxial block, with varying results. Dexamethasone is a synthetic glucocorticoid steroid commonly used in the perioperative setting for a multitude of indications, including the prolongation of local anesthetic based analgesia. It has been shown that the administration of dexamethasone either intravenously or via perineural injection can significantly increase the duration of analgesia derived from a local anesthesia based peripheral nerve block. Literature also suggests that the effect of dexamethasone is equivalent whether given intravenously or perineurally. Interest in dexamethasone enhanced caudal analgesia exists and a previous study noted that caudal anesthesia can be prolonged by intravenous dexamethasone. The study was criticized for using a higher dose of dexamethasone (0.5 mg/kg) than is routinely used in the pediatric population outside of airway procedures, which may expose patients to dose related side effects of dexamethasone. A large meta-analysis has suggested that 0.1 mg/kg is effective for analgesic prolongation, but no direct study of low dose intravenous dexamethasone in combination with caudal anesthesia has been performed.
To identify a better method using a combination of routine anesthetic drugs to improve hemodynamic stability during Mayfield head pinning for craniotomy surgery.
The Foley catheter is one component in a catheter insertion procedure that could contribute to a catheter associated urinary tract infection (CAUTI). Improvement in the catheter insertion procedures using the ERASE CAUTI Tray system may help to lower these infection rates.
It has been shown that N-methyl-D-aspartate (NMDA) receptor antagonists (such as ketamine) potentiate analgesic drug's efficacy. Polyamines are allosteric modulators of NMDA receptors. In animal studies, polyamine-free diet has shown antinociceptive properties. This research aims at evaluating analgesic properties of polyamine-low diet after laparoscopic cholecystectomy performed in an ambulatory setting.
The use of deep sedation may improve the quality of recovery of patients undergoing minor gynecologic procedures. These patients may also have shorter hospital stays and potentially lower healthcare costs. Additionally, the use of deep sedation for second trimester pregnancy termination may be associated with less bleeding, a smaller decrease in perioperative hemoglobin and better quality of recovery.
In patients undergoing laparotomy, the incidence of abdominal wall related complications such as incisional hernia is very high. In particular in patients with peritonitis undergoing laparotomy the incidence of incisional hernia is up to 54.3%. Furthermore, these patients are at great risk for development of postoperative fascial dehiscence. The gold standard of abdominal wall closure is a running slowly absorbable suture irrespective of the presence of peritonitis. Implantation of an intraperitoneal mesh potentially reduces the incidence of incisional hernia. In a series of high risk patients in which we implanted non-absorbable intraperitoneal mesh prophylactically we reduced the incidence of incisional hernia down to 3.2%.
This study wants to compared the safety and efficacy of GDTs using standard pressure-related parameters vs. dynamic hemodynamic indices associated with fluid compartment monitoring, in septic patients requiring emergency surgery.

The skin conductance algesimeter (Pain Monitor™, Med-Storm Innovation AS, NO-0264 Oslo, Norway)) reflects the sympathetic nervous system by the measurement of the skin conductance of the palm of the hand. SCA detects nociceptive pain fast and continuously, specific to the individual, with higher sensitivity and specificity than other available objective methods. The skin conductance response to a calibrated noxious stimulus varies among patients. It defines two types of people depending on its magnitude. The investigators assume that the importance of skin conductance response to a noxious stimulus predicts the occurrence of chronic pain in patients operated by thoracotomy.
