Case discussed w/attending. Plan to CT head, and suture and release if benign read.
Hours later, CT has not been read and radiology cannot be reached. Next shift attending reviews CT w/medical student and no abnormalities are noted. Pt is sutured and prepared for discharge.
Hospital Course
Lidocaine w/epi on face (before irrigation): ◦ Max dose 7 mg/kg ≈ Given 4 ml locally
◦2 ml as nerve block in supraorbital notch How much water & what kind for irrigation?
◦60 ml/cm ≈ 240 ml of clean H2O (NaCl, tap, etc) Sutured inner & outer layers:
◦5 stitches with 4.0 Vicryl on inner layer,
◦16 stitches with 5.0 Nylon on skin
◦ Can be left open to air, cleaned with soap and water When to come back/why to come back
o 5 days post forehead lac for removal & f/u
Suturing
Original attending of case reviews CT “Mildly depressed fracture anterior wall left
frontal sinus. Soft tissue defect of left frontal scalp.”
ENT is consulted, but pt leaves AMA prior to exam.
Nine days later pt returns to ED for suture removal. Laceration is healing well, with no swelling/ erythema or associated pain.
- ROS, no HA/dizziness/lightheadedness/rhinorrhea.
Appointment is scheduled with ENT for following day. Pt does not attend.
