ABSTRACT
Background@#Hemodynamic instability can occur with the pain from scalp incision to brain retraction during cranial neurosurgery. @*Objective@#To determine the hemodynamic outcomes of patients who received ropivacaine plus lidocaine scalp block. @*Design@#Retrospective cohort study. @*Setting@#Southern Philippines Medical Center, Davao City. @*Participants@#44 patients given scalp block for cranial neurosurgery. @*Main outcome measures@#Heart rate (HR), mean arterial pressure (MAP), and frequencies of tachycardia, hypertension, bradycardia, and hypotension from the time of scalp block administration to 15 minutes after scalp incision (observation period).

Objective: To investigate the hemostasis effect of hemocoagulase for injection in scalp incision in craniocerebral surgery, and evaluate its effect on coagulation function and drug safety. Methods: Before undergoing craniotomy, 60 patients were randomly divid-ed into the study group and the control group. The study group was injected with hemocoagulase for injection at 1u im at the night before surgery, 1u im 1h before incision and 1u im 15min before incision. The control group was injected with 0. 9% saline at the same time with the same volume. The hemorrhagic volume, hemorrhagic volume per square decimeter, hemostatic time, blood coagulation and ad-verse events were tested and compared between the groups. Results: In the study group, the mean hemorrhagic volume was (37. 18 ± 2. 96)g, the mean hemorrhagic volume per square decimeter was (0. 23 ± 0. 16)g·cm-2and the mean hemostatic time was (125. 53 ± 36. 42)s. In the control group, the corresponding value was (60. 69 ± 2. 30) g, (0. 42 ± 0. 25) g·cm-2and (182. 72 ± 52. 29) s, re-spectively. The hemorrhagic volume, hemorrhagic volume per square decimeter and hemostatic time significantly decreased in the study group when compared with those in the control group (P<0. 05). No significant difference in blood coagulation and safety (P>0. 05). No adverse event was reported. Conclusion: Hemocoagulase for injection shows promising hemostasis effect with high safety, which can ensure craniocerebral surgery going well with shortened operation time.
ABSTRACT
Objective To explore an effective and safe therapeutic strategy in the treatment of coronoid process fracture com‐bined with ipsilateral zygomatic arch fracture .Methods Through the semi coronoid scalp incision ,`an open reduction and internal fixation of zygomatic arch fracture was done .The operation was modified that the area of zygomatic arch fracture was exposed ade‐quately ,and then the fracture fragments of zygomatic arch were turned up .The coronoid process fracture pieces were isolated and removed along with the direction of muscle fibers in the temporalis muscle .Results All Cases of the surgical incisions were healed by primary intention .After 3 - 24 months following up ,the function of mouth opening and closing ,and the other movements of mandible became normal .Conclusion Through the semi coronoid scalp incision ,zygomatic arch fracture reduction and internal fixa‐tion and the coronoid process fracture pieces removing can be done simultaneously .In this way ,an effective and safe therapeutic strategy for treating coronoid process fracture combined with ipsilateral zygomatic arch fracture .
