    An add-on therapy for neuropathic pain: Infiltration block with diclofenac sodium and lidocaine through the hypertrophic scar tissue
    (2019) Eker, Hatice Evren; Yalcin Cok, Oya; Bozdodan Ozyilkan, Nesrin; Aribodan, Anis; 30633313
    In some situations, the cause of the supposed neuropathic pain might be related to abnormal tissue recovery such as scar formation due to wound retraction that might create mechanical compression on the nerve tissue. In this report we describe infiltration block with diclofenac sodium and lidocaine through the hypertrophic scar tissue to reduce mechanical stress in 3 patients. The infiltration technique might resolve the tension of the contracted scar tissue by tearing the adhesions and the eliminated mechanical compression would reduce the pressure on nerve tissue and hence neuropathic pain symptoms.

    Ketamine dosing for sedation during repeated radiotherapy sessions in children
    (2018) Yalcin Cok, Oya; Evren Eker, Hatice; Aribogan, Anis; 30119163
    Background/aim: We report the analysis of ketamine doses needed and the recovery tones in pediatric oncology patients undergoing repeated radiotherapy sessions. Materials and methods: In a single-blind prospective study design, thirty-three pediatric patients undergoing radiotherapy due to oncologic disorders received 2 mg/kg ketamine and 10 mu g/kg atropine intravenously and the rescue drug to be administered was ketamine at 0.5 mg/kg when the sedation level was inadequate. Total ketamine consumption, additional doses, and recovery time were recorded. Results: Data of 635 consecutive radiotherapy sessions were evaluated. There was no significant alteration in total ketamine consumption required to complete the radiotherapy periods during consecutive procedures (P > 0.05). However, the recovery times started to decrease by the fourth session (P = 0.02) and continued to decrease onwards during the whole study period (P = 0.001). The mean of the first recovery time was 13.68 +/- 3.99 min, whereas the mean of the last recovery time was 7.66 +/- 6.35 min. Conclusion: A requirement for an incremental increase in ketamine dose after subsequent administrations was not detected, despite a significant decrease in recovery times being anticipated when ketamine is used repeatedly for sedative purposes in consecutive radiotherapy sessions.
