Intensive Care Complications in Liver and Multivisceral Transplantation

Haemodynamic effects of physiotherapy programme in intensive care unit after liver transplantation

OBJECTIVE

To determine the haemodynamic effects of intensive care physiotherapy after liver transplantation.

PATIENTS AND METHODS

Thirteen patients were included in the study after liver transplantation. The following physiotherapy programme were applied to the patients in intensive care unit: Respiratory physiotherapy, active joint movements, sitting in bed (first task), sitting at the edge of bed (second task), standing (third task), sitting out of bed (fourth task) and walking (fifth task). Heart rate (HR), mean, systolic and diastolic blood pressures (MBP, SBP, DBP), peripheral oxygen saturation (SpO(2)), respiration rate (RR) were recorded before treatment, after each task, after treatment and at the fifth minute of recovery. Pain level was assessed with Visual Analogue Scale (0-10).

RESULTS

When compared with supine position before treatment, all of the parameters except RR increased after the first task whereas HR, SBP, MBP and pain increased after the second task. After the third task only HR and pain increased. There was no significant difference between the fourth task and pre-treatment values while HR, DBP and pain increased after the fifth task. When measurements of pre-treatment, immediately after treatment and the fifth minute of recovery were compared HR, MBP and pain increased after treatment whereas HR, RR and pain decreased after recovery. There was no significant difference between pre-treatment values and fifth minute of recovery measurements.

CONCLUSION

Returning to initial values after a 5-min period shows that cardiopulmonary changes caused by intensive care physiotherapy after liver transplantation are responded at physiological limits.

Electrolyte imbalances in pediatric living related small bowel transplantation

BACKGROUND

Pediatric small bowel transplantations are associated with pronounced electrolyte disturbances in the postoperative period. We investigated the pattern of electrolyte disturbances with regard to enteral malabsorption, renal compensation, and the influence of immunosuppression.

METHODS

We reviewed 11 small bowel transplantations between October 2002 and February 2007. The data collected included frequent serum, ostomy, and urine electrolyte profiles, renal function parameters, and FK 506 levels in the postoperative period up until either discharge or graft loss.

RESULTS

Our results show enteral losses most prominent during the first 4 weeks postoperatively that are only partially compensated by the kidneys. Subsequently, enteral losses improved, although renal function remained challenged, particularly glomerular filtration and phosphorus, magnesium losses, which correlated with high FK 506 levels.

CONCLUSION

Our data reveal several electrolyte imbalances different and unique to postoperative small bowel transplants. Although enteral losses improve along with graft villi formation, electrolyte abnormalities continue, to which FK 506-mediated renal toxicity might contribute.

Short bowel syndrome

Treatment of short bowel syndrome (SBS) is often a difficult endeavor due to the high variability among patients with SBS in regard to remaining anatomical structure and functional capacity. Research efforts to substantiate the use of existing therapies in the treatment of SBS are ongoing, with newer developments yet to be fully explored. Current therapy for SBS begins with the implementation of a modified diet based on the presence or absence of the colon. Patients with difficulty ingesting enough nutrients and fluids for weight maintenance and fluid balance may benefit from nocturnal enteral nutrition and hydration. Those with inadequate absorptive capacity despite maximization of oral and enteral intake will need parenteral nutrition (PN) or hydration. Medications, including antisecretory agents, antidiarrheals, pancreatic enzymes, bile acid sequestrants, and antibiotics, often are useful in abating symptoms commonly associated with SBS. Growth factors, including recombinant human growth hormone and glucagon-like peptide 2, may be trialed to stimulate intestinal adaptation and enhance absorption in PN-dependent SBS patients. The gradual refinement of surgical procedures for SBS, including small bowel transplantation, has led to improved outcomes, and early referral of SBS patients to centers of excellence will optimize care.
