Background: The somatotype is defined as the quantification of the present shape and composition of the human body. It can be simply categorized into 4 groups (Endomorphy, mesomorphy, ectomorphy and central group). Some studies show that mesomorphic component positively correlate to lean body mass which is acceptable proved that loss of lean body mass more than 25-30 % results in fatal outcomes in critically ill surgical patients. Because there is no study that prove the association between somatotype and outcomes in critically ill surgical patients. Therefore, the purpose of this study was to prove the association of the somatotype and the outcomes in critically ill surgical patients.
Patients and Methods: A total of 200 critically ill surgical patients in surgical intensive care unit at Maharaj Nakorn Chiang Mai hospital were collected. Demographic data and outcomes (28-day mortality rate, Hospital length of stay, ICU length of stay and duration of ventilator use) were compared among 4 groups of somatotypes (endomorphy, mesomorphy, ectomorphy and central group)
Results: There was no significant difference in outcomes of critically ill surgical patients between 4 groups of somatotypes (endomorphy, mesomorphy, ectomorphy and central group). The 28-day mortality rate are 0%, 16.7%, 14.9%, 8.6% (p = 0.15) in endomorphy, mesomorphy, ectomorphy and central group respectively. The median length of hospital stay was 15, 19, 31, 20 days (p = 0.21) respectively. The median length of ICU stay was 14, 7, 12, 8 days (p = 0.36) respectively. The median duration of ventilator use was 12, 5, 12, 7 days (p = 0.38) respectively.
Conclusion: This study shows that no significant difference in outcomes of critically ill surgical patients between 4 groups of somatotypes. 28-day mortality rate, length of hospital stay, length of ICU stays and duration of ventilator use.
