Surgical Apgar Score for Identifying Patients Who May Need Intensive Care After Emergency Abdominal Surgery (SAS-ICU)

6. september 2026 oppdatert av: King Edward Medical University

Surgical Apgar Score Predicts ICU Admission After Emergency General Surgery Laparotomy

This prospective observational study will evaluate whether the Surgical Apgar Score can help identify patients who require direct admission to the intensive care unit after emergency abdominal surgery. The study will include patients aged over 12 and under 90 years undergoing emergency exploratory laparotomy at Mayo Hospital Lahore. The Surgical Apgar Score will be calculated immediately after surgery using three routinely recorded intraoperative factors: estimated blood loss, lowest mean arterial pressure, and lowest heart rate. Patients will be categorized into low Surgical Apgar Score (≤7) and high Surgical Apgar Score (>7) groups. The frequency of direct intensive care unit admission will be compared between the two groups to determine whether a low Surgical Apgar Score is associated with increased need for postoperative intensive care.

Detaljert beskrivelse

Emergency general surgery laparotomy is associated with a substantial risk of postoperative complications and may require postoperative intensive care. In resource-limited healthcare settings, appropriate identification of patients who are likely to require intensive care may assist in postoperative triage and rational allocation of limited critical care resources.

The Surgical Apgar Score (SAS) is a simple 10-point perioperative risk score calculated using three intraoperative parameters: estimated blood loss, lowest mean arterial pressure, and lowest heart rate. Lower scores have been associated with increased postoperative morbidity and mortality in several surgical populations. Previous studies have also reported an association between low SAS and direct postoperative intensive care unit admission. However, evidence regarding its utility among patients undergoing emergency general surgery laparotomy in the local setting is limited.

This study will prospectively observe patients undergoing emergency exploratory laparotomy at Mayo Hospital Lahore and evaluate the relationship between the Surgical Apgar Score and direct postoperative intensive care unit admission. The score will be calculated immediately after surgery using routinely documented intraoperative parameters. Patients will subsequently be categorized according to their SAS, with scores of 7 or less classified as low and scores greater than 7 classified as high.

The study will determine the frequency of direct intensive care unit admission and assess whether patients with a low Surgical Apgar Score are more likely to require direct postoperative intensive care than those with a higher score. Relevant demographic and clinical characteristics will also be recorded to allow assessment of factors that may influence the relationship between SAS and intensive care admission.

The findings may help determine whether the Surgical Apgar Score can serve as a simple and readily available tool for identifying emergency laparotomy patients at increased risk of requiring postoperative intensive care. This may support more objective postoperative triage and resource allocation in high-volume, resource-constrained surgical settings.

Studiepopulasjon

Patients presenting to Mayo Hospital Lahore who undergo emergency exploratory laparotomy for emergency general surgery pathology will be enrolled consecutively. Eligible participants will include males and females aged 13-89 years undergoing emergency laparotomy within 8 hours of surgical evaluation. The study population will include patients undergoing laparotomy for conditions such as gastrointestinal perforation, intestinal obstruction, intra-abdominal sepsis, ischemia, and blunt or penetrating abdominal trauma. The Surgical Apgar Score will be calculated immediately after surgery using estimated blood loss, lowest intraoperative mean arterial pressure, and lowest intraoperative heart rate. Patients will subsequently be classified according to direct postoperative ICU admission.

Patients who provide informed consent for participation.

Exclusion Criteria:

  • Patients transferred from another emergency institution when more than 8 hours have elapsed since initial presentation.

Kohorter og intervensjoner

Gruppe / Kohort
Low Surgical Apgar Score (≤7)
Participants undergoing emergency exploratory laparotomy who have a Surgical Apgar Score of ≤7, calculated immediately after surgery from estimated blood loss, lowest mean arterial pressure, and lowest heart rate recorded during the operation. This cohort will be observed for direct admission to the intensive care unit following surgery. No intervention is assigned as part of the study.
High Surgical Apgar Score (>7)
Participants undergoing emergency exploratory laparotomy who have a Surgical Apgar Score of >7, calculated immediately after surgery from estimated blood loss, lowest mean arterial pressure, and lowest heart rate recorded during the operation. This cohort will be observed for direct admission to the intensive care unit following surgery. No intervention is assigned as part of the study.
