Minute-to-minute urine flow rate variability: a retrospective survey of its ability to provide early warning of acute hypotension in critically ill multiple trauma patients.

Purpose: Dynamic changes in urine output and neurological status are the recognized clinical signs of hemodynamically significant hemorrhage. In the present study, we analyzed the dynamic minute-to-minute changes in the UFR and also the changes in its minute-to-minute variability in a group of critically ill multiple trauma patients whose blood pressures were normal on admission to the ICU but who subsequently developed hypotension within the first few hours of their ICU admission.

Patients And Methods: The study was retrospective and observational.

Electricity: How Much for the Contemporary Tertiary Care Operating Room? A Case Report.

Surgery requires many electrically driven devices. Three events occurred recently in an operating room (OR) suite circa the 1980s wherein circuit breakers tripped due to overloaded circuits. This led to us to (1) increase OR electric capacity; (2) record each instrument's power requirements, map their OR location, and determine when during surgery they were used; (3) provide users with instruction and diagrams into which outlet to plug each instrument.

Urine flow rate monitoring in hypovolemic multiple trauma patients.

Background: The urine output is an important clinical parameter of renal function and blood volume status, especially in critically ill multiple trauma patients. In the present study, the minute-to-minute urine flow rate and its variability were analyzed in hypotensive multiple trauma patients during the first 6 h of their ICU (intensive care unit) stay. These parameters have not been previously reported.

Minute-to-minute urine flow rate variability: a new renal physiology variable.

Background: Urine output is a surrogate for tissue perfusion and is typically measured at 1-hour intervals. Because small urine volumes are difficult to measure in urine collection bags, considerable over- or underestimation is common. To overcome these shortcomings, digital urine meters were developed.

The current status of continuous noninvasive measurement of total, carboxy, and methemoglobin concentration.

Intraoperative early detection of anemia, identifying toxic levels of carboxyhemoglobin after carbon monoxide exposure and titrating drug dosage to prevent toxic levels of methemoglobin are important goals. The pulse oximeter works by illuminating light into the tissue and sensing the amount of light absorbed. The same methodology is used by laboratory hemoglobinometers to measure hemoglobin concentration.

Automatic computerized endotracheal tube position verification: an animal model evaluation.

Background: Improper endotracheal tube positioning carries a high risk for morbidity and mortality; verification and confirmation of correct placement is necessary. We propose a computer-automated identification of endotracheal tube positioning using image analysis. The end product will not retain a monitor; rather, the acquired image will be automatically analyzed by a mini electronic processor.

Automatic endotracheal tube position confirmation system based on image classification--a preliminary assessment.

Endotracheal intubation is a complex medical procedure in which a ventilating tube is inserted into the human trachea. Improper positioning carries potentially fatal consequences and therefore confirmation of correct positioning is mandatory. This paper introduces a novel system for endotracheal tube position confirmation.

Urine flow is a novel hemodynamic monitoring tool for the detection of hypovolemia.

Background: Noticeable changes in vital signs indicating hypovolemia occur only after 15% of the blood volume is lost. More sensitive variables (e.g.

Novel automatic endotracheal position confirmation system: mannequin model algorithm evaluation.

Objective: A novel endotracheal intubation accurate positioning confirmation system based on image classification algorithm is introduced and evaluated using a mannequin model.

Methods: The system comprises a miniature complementary metal oxide silicon sensor (CMOS) attached to the tip of a semi rigid stylet and connected to a digital signal processor (DSP) with an integrated video acquisition component. Video signals acquired and processed by an algorithm implemented on the processor.

Early management of the traumatized airway.

Penetrating face and neck trauma is usually obvious, but blunt trauma mandates high index of suspicion to recognize its existence. Comprehensive understanding of the injury is mandatory to plan the best timing and method to secure the airway.

Conventional terrorist bomb incidents and the intensive care unit.

Purpose Of Review: A terror bombing creates a momentary stress on acute care services, including the emergency medical system, emergency departments, and intensive care units. A knowledge of the progression of events, the anticipated volume of injured survivors, and the pattern of injuries will enable the physician in the intensive care unit to prepare the unit quickly and efficiently for the expected rush of injured survivors.

Recent Findings: In the past 2 years it has become apparent in the medical literature that terror bombing causes more complicated injuries than other types of trauma.

Multiple casualty terror events: the anesthesiologist's perspective.

Unlabelled: In a 28-mo period 14 multiple-casualty terror events occurred in Jerusalem, challenging the Department of Anesthesiology and Critical Care Medicine of the city's sole Level 1 trauma center. We performed a retrospective review of the response of the department to evaluate staff activities, resource use (emergency department, operating rooms, and intensive care unit [ICU]), and patient flow. A total of 1062 people were injured in the 14 multi-casualty terror incidents.
