Gastric tonometry correlates with the severity of blood loss during shock. However, tonometry is cumbersome, has a slow response time, and is not practical to apply in the acute resuscitation setting. We hypothesized that subcutaneous tissue (SC) and skeletal muscle (SM) pH, pCO2, and pO2 changes are comparable with changes seen in bowel tonometry...

Continuous monitoring of pH, Pco2, and Po2 using fiberoptic sensor technology has been proposed recently as a clinical monitor of the severity of shock and impaired tissue perfusion. Surrogates of gut tissue perfusion such as gastric tonometry, although cumbersome, have been used to indirectly quantify the degree of gut ischemia. The purpose of thi...

Background: Continuous monitoring of pH, Pco2, and Po2 using fiberoptic sensor technology has been proposed recently as a clinical monitor of the severity of shock and impaired tissue perfusion. Surrogates of gut tissue perfusion such as gastric tonometry, although cumbersome, have been used to indirectly quantify the degree of gut ischemia. The pu...

Hemostasis is crucial during laparoscopic surgery. Unlike conventional electrosurgery, saline-enhanced electrosurgery (SEE) improves the electrode-to-tissue interface. This study investigated SEE as a means of achieving hemostasis in liver and splenic injuries and assessed the associated histologic changes. Nine anesthetized pigs underwent laparosc...

Continuous assessment of tissue perfusion and oxygen utilization may allow for early recognition and correction of hemorrhagic shock. We hypothesized that continuously monitoring skeletal muscle (SM) PO2, PCO2, and pH during shock would provide an easily accessible method for assessing the severity of blood loss and the efficacy of resuscitation. T...

Pyruvate has been shown to be protective in numerous in vitro and in vivo models of oxidant-mediated cellular or organ system injury. Unfortunately, the usefulness of pyruvate as a therapeutic agent is abrogated by its very poor stability in solution. In an effort to take advantage of the ability of pyruvate to scavenge reactive oxygen species whil...

Continuous assessment of tissue perfusion may allow for early detection and correction of hemorrhagic shock. We investigated continuously monitoring pH, pO2 and pCO2 of skeletal muscle (SM), subcutaneous tissue (SQ) and bladder wall (BW) as possible sites for following the course of hemorrhagic shock and resuscitation.

There are several anxiety-related reactions associated with magnetic resonance imaging (MRI). Patients who experience such reactions may disrupt the examination or move so much that images are degraded. These experiences may also influence patients' perceptions of the quality of their care. The objective of this study was to further assess the subj...

Monitoring treatment efficacy in patients with portal venous hypertension has been limited by the difficulty of direct or indirect assessment of portal vein pressure. The majority of currently available haemodynamic tests, such as hepatic vein wedge pressure or azygos vein flow measurement by thermodilution catheter, are invasive which has restrict...

Two examples of a marked defect of the corner of the vertebral body adjacent to an intervertebral disk herniation are presented. The prevalence of this finding was assessed in 43 randomly selected patients with disk herniation (at 46 levels). None of these patients had such marked vertebral defects (moderate changes at 3 levels; minor in 23). Altho...

We have studied 100 patients undergoing magnetic resonance imaging (MRI) in eight well-defined clinical problems. The relative values of the clinical details and the initial imaging sequence in reaching the final MR diagnoses were assessed. For each patient, two radiologists independently predicted the likely radiological findings from the clinical...

A technique for assessing regional left ventricular function using magnetic resonance imaging is described. Spatial modulation of magnetization (SPAMM) is effected immediately before images are obtained at various intervals during the cardiac cycle using a modified field echo even rephasing technique (FEER). By performing such modulation in two pla...

An audit was undertaken of the use of magnetic resonance imaging for clinical problems of the head and spine. Using a form of simulation, two consultant clinicians were asked to assess a sequential series of 200 patients referred for magnetic resonance. The clinicians considered that 200 magnetic resonance studies could replace about 330 other imag...

To test how the results of magnetic resonance imaging influence clinicians' diagnoses and management plans for patients with cranial and spinal problems and to assess changes in the quality of life of these patients. Survey of patients undergoing cranial and spinal magnetic resonance imaging with questionnaires about diagnoses and intended manageme...

Magnetic resonance imaging was performed in 35 patients with breast carcinoma in an attempt to elucidate the cause for arm oedema or neurological symptoms. In each patient the clinician was asked to predict at the outset whether tumour recurrence or radiation fibrosis was more likely on clinical grounds. MRI demonstrated features compatible with fi...

Twenty elderly patients (mean age 82 years) with dizziness were examined by magnetic resonance imaging (MRI). The findings have been compared with those from nine healthy subjects of similar age who acted as a control group. The technique proved acceptable to all these patients, and in the majority (65%) the overall radiographic quality of the resu...

Three hundred and sixteen patients who suffered a subarachnoid haemorrhage of unknown cause were followed up by questionnaire after 2 to 23 years, the average interval being 10 years. Two hundred and fifty one (79.5%) are known to be alive, 49 (15.5%) had died, and 16 (5%) patients were untraceable. The cumulative survival for the whole group after...

A series of cranial images obtained at three magnetic field strengths in a volunteer on a fast ramp magnetic resonance system is presented. This study was undertaken in the space of 5 h.

A factorial study was designed to examine the effects of fruit maturities, juice extraction temperatures, storage time, and storage temperature on the quality of ‘Concord’ grape ( Vitis labrusca L.) juice. Mature grapes produced juice with superior sensory quality and better objective color initially than less-mature grapes, but juice from grapes a...

The response of 4 erect blackberry cultivars to 2 levels of soil moisture and 2 hedge pruning heights was evaluated. Supplemental irrigation increased yield on all cultivars, but was most effective for the highest-yielding cultivar, ‘Cherokee,’ during the first harvest season (6.03 T/ha for irrigated plots compared to 4.22 T/ha for nonirrigated plo...

A study was designed to examine the effects of production systems (i.e., standard bed, wide bed, and black plastic bed), a high and low plant population, and 3 harvest dates on the machine-harvested yield and quality of 2 strawberry ( Fragaria × ananassa Duch.) clones. ‘Cardinal’ produced higher yields than A-5344, but had poorer quality. The wide-...

Two cultivars of strawberries originally harvested for fresh market were held under 5 postharvest storage treatments and then dipped in one of 4 chemical treatments. The berries were sliced or left whole, dipped, and then processed by freezing or thermal processing. The processed product from ‘Cardinal’ was superior to that from ‘Sunrise’ in this s...

A 4-year study was conducted on ‘Niagara’ grapes ( Vitis labrusca L.) to examine the effects of 3 pruning severities (based on nodes retained), 3 levels of nodes/bearing unit (3, 6, and 9), 2 training systems [Geneva Double Curtain (GDC) and Bilateral Cordon (BC)], and 2 canopy management treatments (shoots positioned and shoots not positioned) on...

Yields on ‘Concord’ grape ( Vitis labrusca L.) increased as pruning severity was decreased until the 6th and last year of this study, at which time the yields tended to equalize between the 30 + 10, 50 + 10, and 70 + 10 pruning treatments. By the last year, vines pruned to the 70 + 10 level produced fruit of unacceptable quality. When the 3-node sp...

(2-Chloroethyl)phosphonic acid (ethephon) was sprayed on irrigated and non-irrigated erect (‘Cherokee’ and ‘Comanche’) blackberries ( Rubus , subgenus Eubatus ) before the first harvest and after the second harvest at 1000 and 1500 ppm. ‘Cherokee’ had higher and more concentrated yields and better color than ‘Comanche’. Dripirrigation increased yie...
