Operating Room

The fundamental objective of staged laparotomy is to accomplish definitive operative management in a calculated, stepwise fashion based on the patient’s physiologic tolerance. This important concept has emerged from collective experience with massive acute abdominal injuries but clearly extends to elective operative procedures and surgical challenges in other torso compartments. Whereas the inability to achieve hemostasis is due most frequently to a recalcitrant coagulopathy following trauma, other scenarios include inaccessible venous injuries, coexisting extraperitoneal life-threatening injuries, uncertain viability of abdominal contents, and the inability to reapproximate abdominal fascia due to reperfusion-induced visceral edema. There are five critical decision-making phases of staged laparotomy: I, patient selection; II, intraoperative reassessment; III, physiologic restoration in the surgical intensive care unit; IV, return to the operating room for definitive procedures; and V, abdominal wall reconstruction. The abdominal compartment syndrome (ACS) is a common, often insidious complication of staged laparotomy. In fact, during phases II and III there is often a delicate balance between effective pressure tamponade of capillary bleeding and the untoward effects of the ACS. During phases IV and V a frequent dilemma is how to enclose the abdominal contents to reduce protein loss and facilitate patient mobilization.

The application of blood conservation strategies to minimise or avoid allogeneic blood transfusion is seen internationally as a desirable objective. Bloodless surgery is a relatively new practice that facilitates that goal. However, the concept is either poorly understood or evokes negative connotations. Bloodless surgery is a term that has evolved in the medical literature to refer to a peri-operative team approach to avoid allogeneic transfusion and improve patient outcomes. Starting as an advocacy in the early 1960s, it has now grown into a serious practice being embraced by internationally respected clinicians and institutions. Central to its success is a coordinated multidisciplinary approach. It encompasses the peri-operative period with surgeons, anaesthetists, haematologists, intensivists, pathologists, transfusion specialists, pharmacists, technicians, and operating room and ward nurses utilising combinations of the numerous blood conservation techniques and transfusion alt...

Background Effective teamwork contributes to patient safety in the operating room (OR). For the busy rural surgeon, enhancing OR teamwork can be difficult. This manuscript describes results from the initial implementation of a preoperative briefing protocol at a rural community hospital. Methods From July 2006 to February 2007, teamwork among OR staff working with a single general surgeon at a rural hospital in Alaska was evaluated before and after introduction of a preoperative briefing protocol. After each case, participants completed a questionnaire applying a 6-point Likert-type scale targeting effectiveness of both the preoperative briefing and OR team interaction. Mean values were calculated from 20 cases before introduction of the preoperative briefing and from another 16 cases after its introduction. Statistical analysis of the difference between pre- and post-protocol team performance was conducted with Student’s t test. Mean procedure times were calculated for matched cases pre- and post-intervention and were compared with Wilcoxon’s exact test. Results Ten members of the OR staff, including the general surgeon, completed both pre- and post-protocol questionnaires. Four additional members of the OR staff completed only pre-protocol questionnaires, and three additional members of the OR staff completed only post-protocol questionnaires. After implementation of the preoperative briefing protocol, the mean score of overall preoperative briefing was 1.01 units higher than before (p p p = 0.057). Conclusions Implementation of a preoperative briefing protocol improved overall preoperative briefing and OR team interaction in the study setting. These findings are encouraging for enhancing teamwork and patient safety through implementation of a systematic protocol.

This paper proposes and evaluates a number of models for building robust cyclic surgery schedules. The developed models involve two types of constraints. Demand constraints ensure that each surgeon (or surgical group) obtains a specific number of operating room (OR) blocks. Capacity con- straints limit the available OR blocks on each day. Furthermore, the number of operated patients per block

Scheduling surgical specialties in a medical facility is a very complex process. The choice of schedules and resource availability impact directly on the number of patients treated by specialty, cancellations, wait times, and the overall performance of the system. In this paper we present a system-wide model developed to allow management to explore trade-offs between OR availability, bed capacity, surgeons’ booking privileges, and wait lists. We developed a mixed integer programming model to schedule surgical blocks for each specialty into ORs and applied it to the hospitals in a British Columbia Health Authority, considering OR time availability and post-surgical resource constraints. The results offer promising insights into resource optimization and wait list management, showing that without increasing post-surgical resources hospitals could handle more cases by scheduling specialties differently.

Preparation for surgery for thoracic intraspinal lesions commonly involves rather difficult X-ray procedures in the operating room. The object of this report is to inform neurosurgeons about a modified technique for preoperative surface localization of intraspinal thoracic pathology. Adhesive, disposable radiographic skin markers placed at the presumed level of an intraspinal lesion are visualized along with the lesion on sagittal magnetic resonance scans of the thoracic spine. The lesion and the skin markers were clearly identified within the same field of view. The lesion itself rather than the vertebral body becomes the reference point for localization. Preoperative imaging with adhesive skin markers facilitates positioning and draping for surgery for thoracic intraspinal lesions. It may even replace intra-operative X-ray procedures in selected cases.

Objective: to analyze intra-hospital results in patients undergoing elective off-pump total arterial revascularization and identify morbidity and mortality predictors using this surgical strategy. Methods: From May 1999 to February 2004, 203 myocardial revascularization procedures with total arterial revascularization without cardiopulmonary bypass (off-pump) were carried out in patients with multivessel disease (three vessels 81.7 %, one vessel disease was excluded). We report pre-surgical variables and co-morbidities: average age 63.9 ± 9.13 years, men 182 (89.5%), hypertension 132 (65%), smokers 125 (61%), hypercholesterolemia 152 (74.8%), previous myocardial infarction (> 30 days) 73 (35%), moderate to severe ventricular dysfunction 31 (15%), redo 5 (2.5%). Total arterial revascularization included T-grafts and sequential grafts with left internal mammary (100%), right internal mammary (56.6%) and radial (63%) arteries. The total number of distal anastomosis was 576 (mean of ...

Overall response rate was 77.1% (2,135 of 2,769). Ratings of teamwork differed substantially by operating room caregiver type, with the greatest differences in ratings shown by physicians: surgeons (F[4, 2058] = 41.73, p < 0.001), and anesthesiologists (F[4, 1990] = ...

Operating theatre represents one of the most critical and expensive hospital resources since a high percentage of the hospital admissions is due to surgical interventions. The main objectives are to guarantee the optimal utilization of medical resources, the delivery of surgery at the right time, the maximisation of profitability (i.e., patient flow) without incurring additional costs or excessive patient waiting time. The operating theatre management is a process very complex: the use of mathematical and simulation models, and quantitative techniques plays, thus a crucial role. The main aim of this paper is to provide a structured literature review on how Operational Research can be applied to the surgical planning and scheduling processes. A particular attention is on the published papers that present the most interesting mathematical (optimization and simulation) models and solution approaches developed to address the problems arising in operating theatres. Directions for future researches are also highlighted.

This article challenges conventional theories about the role of medical photography in the early twentieth century. Some scholars argue that the camera intensified the Foucauldian medical gaze, reducing patients to mere pathologies. Others maintain that with the rise of the new modern hospital and its state-of-the-art technologies, the patient fell from view entirely, with apertures pointing toward streamlined operating rooms rather than the human subjects who would go under the knife. The Army Surgeon General's World War I rehabilitation journal, Carry On: A Magazine on the Reconstruction of Disabled Soldiers and Sailors, problematizes these assumptions. Hoping to persuade a skeptical public that the Army's new programs in medical rehabilitation for disabled soldiers provided the best means of veteran welfare, the editorial officials at Carry On photographed patients fully clothed, wounds hidden, engaged in everyday activities in order to give the impression that the medical sciences of the day could cure permanent disabilities. In the end, Carry On shows us that medical doctors could, and did, use photography to conceal as well as reveal the reality faced by injured soldiers. In doing so, they (like other Progressive reformers at the time) hoped to persuade the public that rehabilitation had the power to make the wounds of war disappear.
