Paragastric Autonomic Blockade to Prevent Visceral Pain After Laparoscopic Sleeve Gastrectomy

Visceral PainBariatric Surgery Candidate6 more

Visceral pain (VP) following laparoscopic sleeve gastrectomy remains a substantial problem. VP is associated with autonomic symptoms, especially nausea and vomiting, and is unresponsive to traditional pain management algorithms aimed at alleviating somatic (incisional) pain. The present study was performed to evaluate the safety and effectiveness of laparoscopic paragastric autonomic neural blockade (PG-ANB) in managing the symptoms associated with VP following sleeve gastrectomy.

Single Dose Safety Study for Compound to Treat Post-Operative Nausea and Vomiting (PONV)

Post-Operative Nausea and Vomiting (PONV)

The purpose of this study is to describe the safety and tolerability and pharmacokinetics of a single intravenous administration of the new, Sulfobutyl Ether-7-Beta-Cyclodextrin (Captisol™) based, formulation in Healthy Adult Subjects.

Effect of Intraoperative Crystalloid Volume on Postoperative Vomiting

Postoperative Vomiting

Postoperative nausea and vomiting is very common in children undergone tonsillectomy and/or adenoidectomy. The purpose of this clinical trial is to evaluate the antiemetic effect of super-hydration with 0.9% saline in children undergoing specifically elective otorhinolaryngological surgery. Fluid intake reduces vomiting as seen following extended period of fasting that interrupts the perfusion in gut. Based on this knowledge, we hypothesized that administration of supplemental fluid would reduce the incidence of postoperative vomiting.

How Pregnant Women and Their Babies Metabolize Ondansetron Compared to a Group of Non-pregnant Women...

Postoperative Nausea

This is called "Aim 1" of the investigators' NIH grant. Ondansetron (Zofran) is a safe and effective drug used in pregnant women to prevent nausea but the investigators do not know what effect pregnancy may have on the metabolism of Zofran in pregnant women or their babies. Therefore the investigators will enroll approximately 40 pregnant women and their babies and draw blood samples from the mother, the baby and the cord, to determine how much Zofran is in each sample of blood (called the pharmacokinetics or PK of Zofran). The pregnant women will receive Zofran, as a standard-of-care drug, for their scheduled Cesarean Section. The investigators will also enroll about 20 non-pregnant women undergoing surgery who will receive Zofran as standard-of-care during surgery. In both the pregnant & the non-pregnant women, the investigators will draw blood samples at the same time points based on number of minutes from the time the Zofran is given. The blood data (PK of Zofran) will help the investigators move into Aim 2 of the study, which will be done in pregnant, narcotic-addicted mothers and their babies who are born addicted to narcotics. Aim 2 will be listed separately as it will be an interventional study.

Dose-ranging Study of Ramosetron for the Prevention of Nausea and Vomiting After Gynecologic Laparoscopic...

Postoperative Nausea and Vomiting

Many patients receiving opioid based analgesia after gynecologic laparoscopic surgery experience postoperative nausea and vomiting (PONV) despite prophylaxis and treatment with HT3 receptor antagonists. Although a high dose of ramosetron can cause adverse effects such as headache or dizziness, the minimal effective dose of ramosetron in a high-risk patients is unknown. The aim of this study is to determine the effective dose of ramosetron for prophylaxis of PONV in a high-risk patients receiving intravenous opioid-based patient-controlled analgesia after gynecological laparoscopic surgery.

Comparison of Two Naloxone Infusion Rates on the Postoperative Recovery of Patients Undergoing Spine...

PainPostoperative2 more

There will be two groups in this study: one group will be given the standard infusion of naloxone, a drug which helps reduce side effects from opioids needed after surgery, and the other group will receive a higher dose. The trial is designed to determine if a higher dose of naloxone infusion will reduce side effects from opioid therapy in patients who have undergone spine fusion for scoliosis.

Efficacy Safety Score in Postoperative Management

PainPostoperative1 more

The primary aim of this project is to determine whether postoperative patients may benefit from the Efficacy Safety Score (ESS) as a tool for postoperative clinical decision support, with a special focus on the first 24 hours after discharge from the postoperative care unit.

Gender Influence on Torsadogenic Actions of Droperidol.

ArrhythmiaDroperidol

Postoperative nausea and vomiting (PONV) is a quite common complication affecting patients undergoing general anesthesia. There are a few pharmacological agents of well known effectiveness in reducing the risk of PONV. One of them is droperidol, which is a butyrophenone derivant. It has been widely used for the prevention and treatment of PONV due to its high effectiveness and low cost. Though, droperidol has a relevant side effect, that is a repolarization prolongation. This can lead to life-threatening cardiac arrhythmias: polymorphic ventricular tachycardia (torsades de pointes, TdP) that can degenerate into ventricular fibrillation and cardiac arrest. This was a reason why in 2001 the FDA issued a "black box" warning on droperidol. Ever since papers focused on this problem have described the influence of small doses of droperidol on TdP genesis as weak. This could be explained by the fact, that QT/QTc (corrected QT) interval prolongation, which represents prolonged cardiac repolarization on ECG, is not the sole determinant of a drug's potential to cause arrhythmia. Another electrocardiographical marker of torsadogenic action is increased transmural dispersion of repolarization (TDR). TDR represents differences in the repolarization between myocardial "layers" (like epicardium, endocardium, myocardium cells). It is believed that the induction of QT/QTc lengthening must coexist with TDR increase at the same time to promote torsadogenic changes. It has been known, on the basis of research, that females have been more potent to torsadogenic actions of pharmacological agents than males. That could be related to estrogen influence on ECG parameters, which had been proven on animal model. It hasn't been investigated, whether gender is an important factor when considering droperidol's torsadogenic potential. The aim of this study is to answer a hypothesis, that women are more potent to torsadogenic actions of droperidol in comparison with men.

Effect of Propofol on Postoperative Nausea and Vomiting.

Postoperative Nausea and Vomiting

As PONV is an unpleasant experience that badly affects the patients' quality of life after surgery and the anti-emetic effects of propofol have been seldomly studied in Pakistan, this study aims at investigation of the beneficial effects of propofol in reducing the occurrence of PONV.
