Essential principles: blood gas analysis

The application of polymerized porcine hemoglobin (pPolyHb) in the rat small bowel preservation

Small bowel transplantation (SBTx) has become a standard clinical treatment for short bowel syndrome or irreversible intestinal function failure. Optimum preservation of the organ is essential for the success of transplantation. In this study, pPolyHb was used as an additive to hypertonic citrate adenine solution (HCA) to provide oxygen for rat small bowel transplant. Rat small bowels were preserved in HCA, HCA with pPolyHb, and University of Wisconsin solution (UW) for 12, 24, and 36 h, respectively. The results suggested that the preservation effect of HCA with pPolyHb was comparable with the UW solution, and more effective than the HCA solution.

Advanced arterial blood gas analysis in septic shock: a Singaporean nursing case review

INTRODUCTION

The admission to the intensive care unit with a diagnosis of sepsis and/or septic shock is not uncommon. The aim of this article is to present a nursing case review of a patient admitted to the intensive care unit with a diagnosis of septic shock and the use of bedside acid-base formulae to inform clinical decision making.

METHOD

We chose to use a case review. This method is useful in reporting unusual or rare cases and is typically seen more in medicine than in nursing.

DISCUSSION

The gentleman in question was a self-presentation with a short history of fever and worsening shortness of breath. His condition worsened where he required admission to the intensive care unit. The use of 'advanced' acid-base interpretation to guide his nursing care provided a platform from which to advance a deeper understanding of the intricacies the critically ill patient often presents.

CONCLUSION

The use of case review is enlightening in understanding the disease process and the decision-making that accompanies this. The lessons learnt are applicable to a wider nursing audience because understanding acid-base physiology is beneficial in supporting and advancing critical care nursing practice.
