Perioperative management of patients with renal disease

Renal effects of general anesthesia from old to recent studies

Various types of anesthesia are being utilized to maintain physiologically secured surgical conditions. Nearly all categories of general anesthesia are characterized by various perioperative and postoperative complications. These shortcomings are important aspects that need to be considered by the anesthesiologist and surgeon before administration of these compounds. The renal effects of anesthesia play an important role in understanding possible systemic changes due to the fact that the kidney has a direct or indirect impact on nearly all the systems of the body. Various studies have been conducted to find out changes in renal parameters and its systemic effects upon administration of the anesthesia and its postoperative repercussions. Besides that, the impaired renal function might have an impact on the excretion of anesthetic metabolites, which can lead to long-term dysfunction. Patients with a previous history of disease ought to be brought under consideration because these chemicals can ameliorate pre-existent symptoms. This review is intended to discuss the early and latest studies based on the effects of general anesthesia on the renal system.

Renal and Gastrointestinal Considerations in Patients Undergoing Elective Orthopaedic Surgery

To minimize perioperative complications after orthopaedic procedures, patients may undergo medical optimization, which includes an assessment of their renal function and gastrointestinal (GI) system. The GI and renal systems are complex, and their proper optimization in the preoperative period can influence the success of any procedure. Several factors can prevent complications and reduce morbidity, mortality, and the cost of care, including a thorough evaluation and screening, with particular emphasis on anemia and its renal and GI causes; management of medications that are metabolized by the liver and excreted by the kidneys; and careful attention to the patient's nutritional status.

Oral health status in haemodialysis patients

OBJECTIVE

To assess the oral and dental manifestations in non- diabetic and diabetic uraemic patients who were undergoing haemodialysis and to estimate and compare the salivary pH in these two groups.

MATERIAL AND METHODS

Ninety Seven uraemic patients who were undergoing maintenance haemodialysis were included in the study. Subjective and objective findings were evaluated and recorded in a specially designed proforma. Predialytic unstimulated whole salivary pH was recorded by using pH-measuring strips. Dental health assessment consisted of DMFT and CPITN indices.

RESULTS

A subjective oral manifestation of dysguesia was found to be more significant in non-diabetic patients (p<0.008). Statistically, a high significance was observed with mucosal petechiae in 31.9% patients of diabetic group .The overall DMFT score was significantly higher in diabetic group. A moderate significance was found with a CPI score of 5 (p<0.015). The pH of saliva was significantly higher among diabetic patients.

CONCLUSION

The diabetic subjects who were on haemodialysis were at a high risk for developing periodontal disease and they exhibited a potential threat for dental decay and xerostomia. A lower salivary pH and a poor glycaemic control may affect their oral health. Further research is required to clarify the combined influence of diabetic nephropathy on oral health.
