AI Article Synopsis
- Spinal surgeries often require patients to lie face down, which can raise intra-abdominal pressure and lead to complications during and after the procedure.
- A case study involving a 74-year-old woman undergoing two spine surgeries showed that using an Allen table resulted in lower intra-abdominal pressure (mean 13.8 mmHg) compared to gel pads (mean 24 mmHg).
- The findings suggest that proper positioning of patients on the abdomen, particularly using the Allen table, may help reduce intra-abdominal pressure and potentially lower the risk of complications in prone surgeries.
Article Abstract
Unlabelled: Spinal surgeries often require prone positioning of the patient. This is associated with increased intra-abdominal pressure, which may increase the risk of intra- and postoperative complications. The described case enables the comparison of two prone positional apparatuses and their influence on changes in intra-abdominal pressure during spine surgeries.
A Case Report: A 74-year-old female patient underwent two spine surgeries due to a fracture of the Th12 vertebra and traumatic kyphosis. Both were performed in the prone position. During the first procedure, stabilization of the fracture, positioning was performed by placing the patient on the Allen table, whereas during the second procedure, laminectomy, by placing the patient on gel pads. During both surgeries the patient's intra-abdominal pressure was measured. The values measured while lying on the Allen table were found to be lower (mean 13.8 mmHg ± 0.66 mmHg) than the results obtained during the procedure utilizing gel pads (mean 24 mmHg ± 1.22 mmHg). Both surgeries were completed without complications. In both cases, creatinine, urea, and potassium concentrations as well as daily diuresis were measured to assess postoperative renal function. The results of these analyses did not indicate renal damage.
Conclusions: The way the patient is positioned on the abdomen has a significant impact on intra-abdominal pressure. Compared to gel pads, the Allen table allows for a reduction in abdominal pressure, which corresponds with lower values of intra-abdominal pressure. This may help reduce the risk of complications during surgeries performed in the prone position.

Few studies today address trans-operative analgesia provided by tramadol without local anesthetics for intra-abdominal procedures. The objective of this study was to assess the efficacy of trans-operative analgesia provided by epidurally administered tramadol in cats undergoing elective ovariohysterectomy. For this purpose, 16 healthy queens were randomly assigned to participate in one of two groups: GC, control group, 0.

Background: Although more risk prediction models are available for feeding intolerance in enteral-nourishment patients, it is still unclear how well these models will work in clinical settings. Future research faces challenges in validating model accuracy across populations, enhancing interpretability for clinical use, and overcoming dataset limitations.
Objective: To thoroughly examine studies that have been published on feeding intolerance risk prediction models for enteral nutrition patients.

Background: The prone position is commonly used in surgical procedures and is known to cause significant hemodynamic changes, particularly a reduction in cardiac output. This study aimed to explore the relationship between intra-abdominal pressure (IAP), airway pressure, and cardiac output during spine surgeries under general anesthesia.
Methods: Twenty-five patients undergoing elective spine surgery in the prone position were enrolled in this prospective observational study.
Background: Intrabdominal pressure (IAP) is an important parameter. Elevated IAP can reduce visceral perfusion, lead to intraabdominal hypertension, and result in life-threatening abdominal compartment syndrome. While ingestible capsular devices have been used for various abdominal diagnoses, their application in continuous IAP monitoring remains unproven.
