研究目的
To present a consecutive case series of patients with improper concentration of sulfur hexafluoride (SF6) applied during vitrectomy.
研究成果
The study highlights the dangers associated with the use of concentrated SF6 in vitreoretinal surgery, including elevated IOP and subsequent complications. It suggests the need for careful use of intraocular gases, proper training of ophthalmic personnel, and the provision of SF6 in a prepared concentration of 20% by manufacturers to prevent such complications.
研究不足
The study is limited by its small sample size and the retrospective nature of the case series. The exact reason for the unexpected gas expansion in one case could not be confirmed.
1：Experimental Design and Method Selection:
The study presents a consecutive case series of patients who underwent vitrectomy with an inappropriate concentration of SF6 applied.
2：Sample Selection and Data Sources:
Three patients who underwent vitrectomy between November 2015 and December 2017 at the Department of Ophthalmology, Elbl?g City Hospital, or the Department of Ophthalmology, Medical University of Gdańsk, Poland.
3：List of Experimental Equipment and Materials:
27-gauge vitrectomy equipment, sulfur hexafluoride (SF6), sterile air, topical dorzolamide, timolol, and brimonidine, intravenous mannitol.
4：Experimental Procedures and Operational Workflow:
Vitrectomy was performed with the administration of SF6 at the end of surgery. Postoperative monitoring of intraocular pressure (IOP) and management of elevated IOP were conducted.
5：Data Analysis Methods:
Case series analysis of patient outcomes following incorrect SF6 concentration administration.
