Aims:
To evaluate the feasibility and efficacy of Mirabilite combined with Lactulose in older patients after abdominal surgery.
Design:
It is a retrospective observational cohort study with a pre and post intervention group.
Methods:
Medical records were retrospectively reviewed of postoperative Intensive Care patients with postoperative gastrointestinal tract dysfunction (aged >60 years) in the Surgical Intensive Care Unit from January 2017-December 2018.
Results:
One hundred and sixty-seven post-surgical Intensive Care patients with postoperative gastrointestinal tract dysfunction were analysed; 74 patients received Mirabilite + Lactulose treatment and 93 patients received Lactulose treatment. The recovery rate of bowel sounds was better in the Mirabilite + Lactulose group (62.16%) compared with the Lactulose group (37.63%) after 3-day treatment (p = 0.002) and the relative risk (RR) was 1.65 (95% CI, 1.20, 2.27). Moreover 70.27% patients in the Mirabilite + Lactulose group finally had flatus or defecation compared with 46.24% patients in Lactulose group (p = 0.003) and the RR was 1.52 (1.17, 1.98). The abdominal girth and Inter Abdominal Pressure in Mirabilite + Lactulose group showed significantly greater decrease over a 3-day period compared with Lactulose group (4.86 vs. 3.46 cm, p = 0.027; 4.80 vs. 3.11 mmHg, p = 0.002 respectively). The pain score had greater decrease from the baseline in Mirabilite + Lactulose group than in Lactulose group (2.40 vs. 1.11; p < 0.01). Patients in the Mirabilite + Lactulose group had shorter hospital stay than the Lactulose group 12.5 (SD 3.51) versus 13.9 (SD 5.14), p = 0.05.
Conclusions:
This study demonstrated that external use of Mirabilite combined with Lactulose can be considered as an easy intervention to improve postoperative gastrointestinal mobility in older intensive care patients who suffer from postoperative gastrointestinal tract dysfunction after surgery.
Impact:
Our results provide a great option to alleviate the sufferings of postoperative patients. The externally use Mirabilite is a painless and safe interventions that is easy to implement by ICU nurses.
Insights
Mirabilite combined with Lactulose improved postoperative gastrointestinal mobility in older patients. This combination therapy enhanced bowel function recovery and reduced hospital stays for surgical intensive care unit patients.
Area of Science:
- Gastroenterology
- Surgical Critical Care
- Pharmacology
Background:
- Postoperative gastrointestinal tract dysfunction (PGITD) is a common complication in older patients following abdominal surgery.
- Effective interventions are needed to improve recovery and reduce patient suffering.
Purpose of the Study:
- To evaluate the feasibility and efficacy of using Mirabilite combined with Lactulose for older patients experiencing PGITD.
- To assess the impact of this combined therapy on gastrointestinal motility and patient outcomes.
Main Methods:
- A retrospective observational cohort study comparing patients who received Mirabilite + Lactulose with those who received Lactulose alone.
- Analysis of medical records from surgical intensive care unit patients aged over 60 years with PGITD between January 2017 and December 2018.
Main Results:
- The Mirabilite + Lactulose group showed a significantly higher recovery rate of bowel sounds (62.16% vs. 37.63%) and a greater incidence of flatus or defecation (70.27% vs. 46.24%).
- This combination therapy led to significant reductions in abdominal girth, inter-abdominal pressure, and pain scores compared to Lactulose alone.
- Patients receiving Mirabilite + Lactulose experienced a shorter hospital stay (12.5 vs. 13.9 days).
Conclusions:
- External application of Mirabilite combined with Lactulose is a feasible and effective intervention for improving postoperative gastrointestinal mobility in older intensive care patients.
- This painless, safe, and easily implementable therapy offers a valuable option for alleviating suffering in postoperative patients with PGITD.
