Development and evaluation of standardized protocol to prevent nasoenteral tube obstruction in cardiac patients requiring enteral nutrition with restricted fluid volumes

[Antiepileptic drugs administration by nasogastric tube in comatose patients]

AIM

To evaluate the modalities of administration of antiepileptic drugs (AED) with nasogastric tube (NGT) by nurses and to draw up recommendations.

METHODS

Our study consisted on investigating the modalities of administration of AED's with NGT by nurses during four months. We prepared 10 questions including demographic information. Participation was voluntary and anonymous. The questionnaire was distributed in seven intensive care departments after authorization of each head of the department. Thus, 45 nurses were included.

RESULTS

Nurses sex ratio was 1.5 and mean age was 31 years (25 to 37 years). Among the nurses, 60% mentioned that the NGT were silicone made and 4% that they were PVC made. The mean duration before replacing the NGT was thought to be 5±3 days. Among the nurses, 91% affirmed to clear the NGT after each use. All the nurses had agreed that the solid form is the most commonly used pharmaceutical form in the NGT. AED were associated with the enteral feeding solution in 56%. The AED should be crushed before administration for 98% of the nurses even in case of polymedication. Among them, 62% recommended to crush all of the associated drugs together. Before introducing the AED into the NGT, 93% of the nurses reported mixing with tap water. We have noticed that 62% of nurses felt the need to improve their knowledge AED administration with NGT.

CONCLUSION

To optimize AED therapy, modalities of administration by NGT in epileptic comatose patients should be enhanced.

Drug-nutrient interactions in the intensive care unit: literature review and current recommendations

OBJECTIVE

To describe the interactions between drugs and nutrients and their frequency in the intensive care unit and to assess the professional team's awareness regarding this subject.

METHODS

The keywords "drug interactions" and "nutrition therapy" were searched in the PubMed (specifically MeSH) electronic database. The studies were systematically reviewed for descriptions of the types of interactions between drugs and nutrients, including their frequency and consequences.

RESULTS

Sixty-seven articles were found. Among these, 20 articles were appropriate for the methodology adopted and accomplished the objectives of the study. Of these 20 articles, 14 articles described interactions between drugs and enteral nutrition, three described interactions between drugs and parenteral nutrition, and three described the importance and care required to avoid such interactions.

CONCLUSIONS

The literature about drug and nutrient interactions is limited and suggests the inability of health care teams to recognize the potential for these interactions. Possibly, the elaboration of a protocol to evaluate drug-nutrient interactions will increase the safety and efficacy of therapeutics.

Incidence of gastric extubation of users in a home care program of a university hospital

This quantitative, prospective study, aimed to characterize the profile of users and caregivers and to measure the incidence of gastric extubation, identifying the type and the reasons for the extubation of these users in a Home Care Program of a university hospital. The population consisted of 37 subjects and the data were collected from April to August 2010. For the analysis, descriptive statistics, test of significance of 5% and calculation of indicators were adopted. It was found that 51.4% of the users were female, 67.5% in the age group >60 years and 67.6% presented neurological diseases. Regarding the caregivers 89.2% were female and their mean age was 50.6 years. The incidence of extubation, considering 100 days of intubation, corresponded to 1.08, with 0.26 planned and 0.82 unplanned (p=0.009). These results allowed the rates to be calculated of the extubation of patients with gastric intubation for nutritional support in domicile care, providing support in establishing care and management goals for the continuous improvement of quality.
