Filter by:This study aims to compare the effects of local wound infiltration with ketamine versus dexmedetomidine when added to bupivacaine on stress response and postoperative pain in lower abdominal cancer surgery.
General anesthesia and mechanical ventilation promotes atelectasis and airway closure. The open-lung approach (OLA) strategy restores the functional residual capacity. Pulse oximetry hemoglobin saturation (SpO2) using room air can diagnose shunt induced by lung collapse during general anesthesia and the SpO2 breathing air was useful to detect the lung´s opening and closing pressure during a recruitment maneuver (RM) in morbidly obese anesthetized patients. Investigators hypothesized that the SpO2 breathing air can personalize the open-lung approach.
This study aims to compare the analgesic efficacy of transversus abdominis-plane block with bupivicaine versus bupivacaine with morphine in patients undergoing major abdominal cancer surgery.
This study will look at how tumors in the chest and abdomen move when you breathe. Your doctors are studying if extra 4D CT scans and instructions on how to breathe can help predict this type of movement and improve the accuracy of radiation treatment. 4D CT scans are approved by the FDA. A 4D CT scan is different from a regular CT because it moves slower and takes more pictures. It takes pictures of the way your body moves when you breathe. This gives doctors more pictures of your body so that they can match your pictures to the way you breathe. In this study, instructions on how to breathe will be visual and audio. Visual instructions will be given to you on a computer screen. You will hear audio instructions through a speaker.
Primary Objective: 1. Compare the duration of postoperative ileus (POI) duration (time to first flatus), subjective reports of surgical and gas pain, postoperative pain medication (total milligrams per 24 hours) and postoperative recovery time(length of stay) between two groups of abdominal surgery cancer patients receiving either standard postoperative care or standard care plus the rocking intervention.
To validate a new method for assessing perioperative risk in the cancer patient undergoing major cancer surgery. In this proposed study researchers will: 1. Measure preoperative energy reserve capacity (fitness) 2. Determine if postoperative morbidity is a function of perioperative cardiopulmonary gas exchange metabolism
Primary Objectives: - To collect accurate and reliable respiration-induced anatomic structure motion data using four-dimensional (4-D) imaging technology. - To analyze these data to study respiration-induced variations and patterns in variations of positions, shapes and volumes of tumors and normal anatomic structures in the thorax and abdomen over a breathing cycle, from one breathing cycle to the next, day-to-day and over the course of radiotherapy. - To assess dosimetric and potential clinical consequences of respiratory motion in the current practice of radiotherapy through preclinical treatment simulation (treatment planning) studies. - To quantify the potential consequences of explicitly accounting for respiration-induced motion on dose distributions and outcome (tumor control probabilities and normal tissue complication probabilities) through preclinical treatment simulation studies. Secondary Objectives: - To investigate the feasibility of using patient training to regulate patient breathing and improve the quality of images and to stratify patients for their eligibility for respiratory-correlated imaging and radiotherapy and for the implementation of various strategies for mitigation of respiratory-induced motion. - To assess the degree of correlation of the marker (or internal anatomic structure such as diaphragm) being tracked as surrogate of breathing with the motion of structures and the intra-fraction and inter-fraction reproducibility of such correlation. - To quantify the effects of radiation therapy on the patterns of respiratory-induced motion of structures through preclinical treatment simulation studies. - To compare various strategies for either accounting for or mitigating respiration-induced motion in the planning and delivery of radiation therapy.
