Template bleeding time for preoperative screening in patients having orthognathic surgery

Predictors of intra-operative blood loss and blood transfusion in orthognathic surgery: a retrospective cohort study in 92 patients

“…The average operating time in this study (the operative time regardless of the addition of the bone graft procedure) was 5 hours and 32 minutes (332 minutes), which is higher than the previously reported times [ 7 , 11 , 14 , 15 ]. We also found a moderate correlation between EBL and the duration of the operation, which is also consistent with other studies [ 13 , 16 ].…”

“…Therefore, in the long-term observation and with a relatively low level of localized inflammation such as in the present study, we could not observe any effect of IL-6 on the periodontal condition changes. For adiponectin, previous studies suggested that periodontal treatment had minimally influenced the serum adiponectin level [9,[39][40][41][42]. The present study added up this relationship, in which serum adiponectin level was relatively minimally influenced by the alteration of the periodontal condition.…”

“…In that respect, we found that in 22 out of 51 papers, the method of measuring estimated blood loss was missing . In 18 out of 51 papers, the estimated blood loss was measured by deducting the volume of saline used from the total volume in the suction unit and by weighing the sponges [31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46][47][48], others 10 mL [43]. In 6 out of 51 papers, losses in sponges were not included Table 1.…”

Current practices of bleeding time in a developing country: an alert for noncompliance with the standard procedures

“…From this survey, the majority of hospitals (75.4%) performed BT for preoperative screening. However, previous studies demonstrated that the BT has poor ability to predict intra‐ or postoperative bleeding from various procedures . Therefore, this indication is inappropriate.…”
