AI Article Synopsis
- Closed suction drainage in arthroscopic ankle surgery does not show significant benefits in reducing swelling, pain, or hospital stay compared to surgery without drainage.
- The study involved 84 patients divided into two groups, with similar outcomes in both groups for swelling and pain levels 48 hours post-surgery.
- The authors conclude that routine insertion of closed suction drains is unnecessary and should be evaluated on a case-by-case basis.
Article Abstract
Introduction: Closed suction drainage is an established procedure in arthroscopic surgery. It is intended to reduce the retention of wound and irrigation fluids, which form the basis for postoperative swelling, pain, and infection. However, currently, there is no scientific review of the actual benefit of this procedure.
Methods: Between 2020 and 2021, 84 patients (53 males, 31 females; mean age: 42 years) were prospectively randomised into this study. The patients underwent arthroscopic surgery of the ankle joint with (group A) or without (group B) insertion of a closed suction drain (42 patients per group). Assessments included upper ankle swelling using the figure-of-eight-20 method, pain preoperatively and 48 h postoperatively, and unexpected events within 6 weeks postoperatively.
Results: The measurements performed 48 h postoperatively showed a mean circumferential increase of 1.38 cm (1.48 and 1.28 cm in groups A and B, respectively; p > 0.05) in all patients. The mean pain at rest, assessed using the visual analogue scale (maximum 10 points), was 2.7 and 2.4 in groups A and B, respectively (p > 0.05). Overall, two minor complications occurred: residual swelling in group A and persistent limitation of movement in group B. The average length of hospital stay was 2.4 days (p > 0.05).
Conclusions: Based on the available data, the routine insertion of a closed suction drainage at the upper ankle does not offer any objective benefit and must be considered obsolete. From both a medical and an economic point of view, the decision to conduct this procedure should be justified on an individual basis.
Level Of Evidence: Level I, prospective randomised trial.

The necessity of routinely placing closed suction wound drainage in spinal surgery has been questioned. This study aims to assess if closed suction wound drainage is necessary for posterior atlantoaxial fixation via intermuscular approach. The functional outcomes of these 40 patients who underwent posterior atlantoaxial fixation via intermuscular approach without drainage tube (Group A) were compared with that of a control group, which consisted of 68 randomly enrolled cases with posterior atlantoaxial fixation via intermuscular approach with drainage tube (Group B).

In this study, a fish scale structure with low viscous drag was proposed and applied to the suction surface of a compressor cascade to reduce total pressure loss and suppress corner separation, a key source of compressor inefficiency. By using CFD simulations, the biomimetic structure was identified and integrated into the cascade design. To evaluate its effects, we analyzed secondary flow structures using 2D projected streamlines, axial velocity density (AVD), and vortex visualization techniques.

Deep sternal wound infection (DSWI) is a rare but potentially devastating complication of median sternotomy performed in cardiac surgery. This report summarizes the nursing management of two pediatric cases with a DSWI treated using Do It Yourself (DIY) negative pressure suction (DIY-NPS) after surgery. The technique maintains a continuous suction pressure of 75 mmHg and intermittently flushes small volumes of fluid to stimulate granulation tissue formation and control systemic infection.

The World Health Organization (WHO) reports 684,000 deaths/year due to slips and falls (SFs), with ∼38 million people requiring medical attention per annum. In particular, SFs on ice surfaces account for 45% of all SF incidents, costing over $100 billion globally in healthcare, intensive care, and insurance expenses. Current antislip solutions focus on hydrophobicity to repel interfacial fluids, aiming to maintain solid-to-solid contact.

Vacuum-assisted delivery (VAD) uses a vacuum cup on the fetal scalp to apply traction during uterine contractions, assisting complicated vaginal deliveries. Despite its widespread use, VAD presents a higher risk of neonatal morbidity compared to natural vaginal delivery and biomechanical evidence for safe VAD traction forces is still limited. The aim of this study is to develop and assess the feasibility of an experimental VAD testing setup, and investigate the impact of traction forces on fetal brain deformation.
