Comparison of octenidine dihydrochloride (Octenisept®), polihexanide (Prontosan®) and povidon iodine (Betadine®) for topical antibacterial effects in Pseudomonas aeruginosa-contaminated, full-skin thickness burn wounds in rats
Pseudomonas aeruginosa is one of the most frequently isolated organisms from infected burn wounds and a significant cause of nosocomial infection
and septic mortality among burn patients. In this animal study, three antiseptic agents which were Octenidine dihydrochloride
(Octenisept®, Schülke & Mayr, Norderstedt, Germany), polyhexanide (Prontosan®, B. Braun, Melsungen AG, Germany) and povidon
iodine (Betadine, Purdue Pharma L.P, Stamford, USA) were compared to assess the antiseptic effect of their applications on
experimental burn wounds in in rats contaiminated with P. aeruginosa. All treatment modalities were effective against P. aeruginosa because there were significant differences between treatment groups and control groups. The mean eschar concentrations were
not different between polyhexanide and povidon iodine groups, but there were significant differences between the octenidine
dihydrochloride group and the other treatment groups, indicating that the Octenidine dihydrochloride significantly eliminated
P. aeruginosa more effectively in the tissues compared to the to other agents. All treatment modalities were sufficient to prevent the
P. aeruginosa invasion into the muscle and to cause systemic infection. In conclusion, Octenidine dihydrochloride is the most effective
antiseptic agent in the treatment of the P. aeruginosa-contaminated burn wounds; Octenidine dihydrochloride can be considered as a treatment choice because of its peculiar ability
of limit the frequency of replacing wound dressings.

- "If there is an open wound on the finger, this should be cleaned and washed with saline solution, and any foreign bodies should be removed. The skin should also be cleaned with povidone iodine . Tetanus prophylaxis in patients with open wounds should be performed according to the vaccination history of the patient  . "

ABSTRACT: Various removal techniques for rings trapped on the finger have been described in the current literature. However, despite this being a frequently encountered situation in emergency departments, there is no comprehensive algorithm to manage and follow these patients in the current literature. The purposes of this study were to describe the most commonly used ring removal techniques and to establish an algorithm for the removal of rings trapped on fingers. We performed a comprehensive literature search in several databases to identify all articles, case reports, letters, and book chapters that focus on ring removal techniques in English language from 1960 to the present. There are 2 methods of removal: (1) noncutting techniques in which the rings can be removed without breaking the integrity of the ring and (2) various ring-cutting equipments and tools. All these techniques are classified into distinct groups and described in detail with illustrations. Furthermore, an algorithm for handling such patients is established according to case-based patient care. Following an algorithm for the removal of trapped rings on the finger will be useful for patients and emergency physicians. It will also prevent possible complications and will save time.

- "Different studies showed that octenidine dihydrochlorid has strong antimicrobial effect against many gram-negative and positive agents and has a low risk of developing resistance [11,14–17]. Uygur et al. , have reported that octenidine dihydrochloride is the most effective agent in the treatment of Pseudomonas aeruginosa contaminated burn wound in vivo. "

ABSTRACT: In this study, our aim is to compare the efficacy of different topical antibacterial agents in a rat model contaminated with a multi drug resistant (MDR) standard Acinetobacter baumannii strain. The study was carried out on 40 Sprague-Dawley rats of 250-300g each. For the purposes of this study, the rats were divided into 5 groups, with 8 rats in each group: Group 1 control; Group 2 silver sulfadiazine; Group 3 mupirocin; Group 4 Acticoat group; and Group 5 octenidine dihydrochloride group. Following to the formation of the full-thickness burn areas in rats, the MDR A. baumannii standard strain was inoculated into the burned area. The rats in all the groups were sacrificed at the end of the 10th day and subjected to histopathological and microbiological evaluation. In the histopathological evaluation, the lowest inflammatory cell response and bacterial density in the eschar and muscle tissues were observed in the Acticoat group. While these results were found to be statistically significant compared to the silver sulfadiazine group, only the bacterial density in the muscle tissue was found as significant in comparison to the mupirocin and octenidine groups. In the microbiological evaluation, the lowest growth in the muscle tissue culture among all the groups was observed in the Acticoat group. The growth in the eschar tissue culture was significantly lower in the Acticoat and octenidine groups in comparison to the silver sulfadiazine group. At the end of the study, it has been observed that Acticoat was effective both in eschar and muscle, while octenidine was effective in eschar tissues in a rat burn model contaminated with MDR A. baumannii.

ABSTRACT: A common challenge of nail avulsion surgery is the associated bacterial contamination and infection that can manifest. The toe has a difficult anatomy to antiseptically prepare and properly maintain throughout the surgical procedure, lending to this widespread problem.
We conducted a controlled, prospective randomized study to examine the antiseptic efficacy of 3 intraoperative irrigation methods during nail avulsion surgery.
We compared intraoperative antiseptic irrigation using 0.9% saline solution (24 patients), 0.2% nitrofurazone (22 patients), and 0.1% polihexanide (25 patients). Swab samples were taken from each patient at 5 distinct stages throughout the surgical procedure, and bacterial culture analysis was performed (positive culture rate, total inocula count, reduction of bacterial load, and identification of specific micro-organisms).
All 3 intraoperative irrigation methods reduced the total bacterial load, but polihexanide was significantly more effective. Furthermore, no patient from the polihexanide group developed postoperative infection. The reduction in bacterial load was lost for all 3 methods after partial nail avulsion surgery, returning to similar values as the initial presurgical bacterial load. An intraoperative irrigation step after partial nail avulsion with saline, nitrofurazone, and polihexanide was effective in reducing the bacterial load by 95.2%, 96.6%, and 99.5%, respectively.
Our patients underwent phenol-based nail avulsion, resulting in no bacterial load after complete nail removal because of the intrinsic antiseptic nature of the phenol.
Intraoperative irrigation with 0.1% polihexanide substantially reduced the bacterial load and subsequent infections, highlighting the importance of an irrigation step in nail avulsion surgery.
