Metabolic response to maxillofacial trauma revisited: A retrospective study

Management of a trauma patient aims at stabilization or resuscitation and revival from critical condition resulting from various sequences of systemic pathophysiological responses in the body. Hematological changes are the first signs reflecting the homeostasis mechanisms starting in the body after injury. The aim of the current study is to evaluate the physiological changes following maxillofacial trauma and extrapolate the findings to understand the posttrauma responses.

This is a retrospective study involving 192 subjects divided into two groups, trauma group and control group. In both the groups, baseline vitals and complete blood picture were recorded for comparison. In trauma group, the recordings were made within 24 h after maxillofacial injury.

All the parameters were analyzed using SPSS version 18. Independent sample t-test was used to assess the nature of data distribution and statistical significance was considered only at P value < 0.05. On comparison of complete blood picture mean values of hemoglobin (13.63 vs 12.18), RBC count (4.51 vs 4.10), WBC count (8835.48 vs 8336.56) were seen to be higher in trauma patients compared to control subjects. The mean bleeding times are almost equal (2.35 vs 2.47) but the clotting times (5.42 vs 5.26), random blood glucose (94.78 vs 90.13), and blood urea (27.14 vs 26.30) were marginally higher in trauma group but were statistically insignificant. The mean value of serum creatinine (0.84 vs 0.80) was comparatively higher in trauma patients and was statistically significant. Study of vitals revealed that mean systolic blood pressures were almost equal (120.65 vs 121.08) in both the groups. The mean diastolic blood pressures (79.46 vs 88.49) and oxygen saturation (93.73 vs 98.86) in trauma patients are comparatively reduced. The mean values of temperature (99.30 vs 98.50) and pulse rate (102.38 vs 97.14) were on relatively higher side in trauma group compared with control group.

Using basic blood parameters and vitals in the present study, the compensatory mechanisms happening in the body after maxillofacial trauma can be seen. These changes although significant on side by side comparison can still fall within the normal physiological range provided by various diagnostic setups. Hence, the need for maxillofacial surgeon to be sensitive to minor variations in these aspects to ensure safety of the patient cannot be overemphasized.
