Surgical Adhesive Drape (IO-ban) as Postoperative Surgical Site Dressing

Wound Closure and Wound Dressings in Adult Spinal Deformity Surgery From the AO Spine Surveillance of Post-Operative Management

STUDY DESIGN

An e-mail-based online survey for adult spinal deformity (ASD) surgeons.

OBJECTIVE

Wound closure and dressing techniques may vary according to the discretion of the surgeon as well as geographical location. However, there are no reports on most common methods. The purpose of this study is to clarify the consensus.

METHODS

An online survey was distributed via email to AO Spine members. Responses from 164 ASD surgeons were surveyed. The regions were divided into 5 regions: Europe and South Africa (ESA), North America (NA), Asia Pacific (AP), Latin America (LA), and Middle East and North Africa (MENA). Wound closure methods were evaluated by glue(G), staples(S), external non-absorbable sutures (ENS), tapes(T), and only subcuticular absorbable suture (SAS). Wound Dressings consisted of dry dressing (D), plastic occlusive dressing (PO), G, Dermabond Prineo (DP).

RESULTS

The number of respondents were 57 in ESA, 33 in NA, 36 in AP, 22 in LA, and 16 in MENA. S (36.4%) was the most used wound closure method. This was followed by ENS (26.2%), SAS (14.4%), G (11.8%), and T (11.3%). S use was highest in ESA (44.3%), NA (28.6%), AP (31.7%), and MENA (58.8%). D was used by 50% of surgeons postoperatively. AP were most likely to use PO (36%). 21% of NA used DP, while between 0%-9% of surgeons used it in the rest of the world.

CONCLUSION

Wound closure and dressings methods differ in the region. There are no current guidelines with these choices. Future studies should seek to standardize these choices.

Surgical site infection at chest tube drainage site following pulmonary resection for malignant lesions

Background

We sometimes experience postoperative surgical site infection (SSI) at the chest tube drainage site (CDS) after thoracotomy. The incidence of and risk factors for SSI at the CDS have remained unclear.

Methods

We conducted a prospective study to determine the incidence and risk factors for SSI at the CDS. We analyzed 99 patients who underwent lobectomy or segmentectomy for pulmonary malignant lesions.

Results

There were 56 males and 43 females with an average age of 71 years. The postoperative drainage period was 2–15 days. Bacterial species were detected in secretions in 18 of 99 cases (18.2%). Older age was a risk factor for the detection of bacteria at the timing of chest tube removal. Eighteen cases (18.2%) were diagnosed with presence of SSI at the CDS at the timing of staple or suture removal. A pathological diagnosis of squamous cell carcinoma was regarded as a candidate risk factor for SSI. Eleven of 18 SSI patients showed delayed wound healing. A higher level of HbA1c was found in patients with delayed wound healing. Enterococcus faecalis infection may influence the development of complex SSI.

Conclusions

We identified the bacterial profiles, incidence of and risk factors for SSI at the CDS. More intense preoperative glycemic control and an understanding of the bacterial profile and may be useful for reducing the incidence of SSI chest tube drainage sites (CDS).

Superficial and Deep Skin Preparation with Povidone-Iodine for Ventriculoperitoneal Shunt Surgery : A Technical Note

Objective

Ventriculoperitoneal (VP) shunt surgery is a common and effective treatment for hydrocephalus and cerebrospinal fluid disorders. Infection remains a major cause of morbidity and mortality after a VP shunt. There is evidence that a deep skin flora microbiome may have a role to play in post-operative infections. In this technical note, we present a skin preparation technique that addresses the issue of the skin flora beyond the initial incision.

Methods

The patient is initially prepped, as standard, with. a single layer of 2% CHG+70% isopropyl alcohol. The novel stage is the ‘double incision’ whereby an initial superficial incision receives a further application of povidone-iodine prior to completing the full depth incision.

Results

Of the 84 shunts inserted using the double-incision method (September 2015 to September 2016), only one developed a shunt infection.

Conclusion

The double incision approach to skin preparation is a unique operative stage in VP shunt surgery that may have a role to play in reducing acute shunt infection.
