PURPOSE: This research examined the quantity of hidden blood loss (HBL) and in contrast perioperative blood loss between minimally invasive transforaminal lumbar interbody fusion (MI-TLIF) and open transforaminal lumbar interbody fusion (O-TLIF).
METHODS: Forty-eight sufferers who had been handled with MI-TLIF and 59 sufferers handled with O-TLIF had been enrolled on this research. Sufferers’ peak, weight, and preoperative and postoperative hematocrit (Hct) had been recorded and used to calculate whole blood loss (TBL) based on the Gross formulation. Every affected person’s HBL was calculated. The knowledge had been additional analyzed by the Scholar t check and the ?2 check.
RESULTS: The seen blood loss (VBL) was 186 ± 95 mL within the MI-TLIF; nevertheless, the HBL (423 ± 233 mL; 66.5 ± 16.1% of TBL) was twice the VBL. The VBL within the O-TLIF group was 471 ± 147 mL, and the HBL was 271 ± 223 mL (31.three ± 23.9% of TBL). Though TBL in MI-TLIF (602 ± 251 mL) was lower than in O-TLIF (742 ± 275 mL), the HBL was considerably larger (P < zero.01). No distinction in postoperative blood loss was noticed between the two teams. Seven and 10 sufferers had preoperative anemia within the MI-TLIF group and the O-TLIF group, respectively, and 32 and 45 postoperatively.
CONCLUSION: HBL is critically underestimated and accounts for a big proportion of TBL in each MI-TLIF and O-TLIF. An accurate understanding of HBL can guarantee affected person security and enhance postoperative rehabilitation.
