Review
INTRODUCTION
Airway injuries are the second leading cause of potentially survivable battlefield death and often require airway management strategies. Airway suction, the act of using negative pressure in a patient's upper airway, removes debris that can prevent respiration, decreases possible aspiration risks, and allows clearer viewing of the airway for intubation. The most important characteristics for a portable airway suction device for prehospital combat care are portability, strong suction, and ease of use.
METHODS
This market review searched academic papers, military publications, Google searches, and Amazon to identify devices. The search included specific characteristics that would increase the likelihood that the devices would be suitable for battlefield use including weight, size, battery life, noise emission, canister size, tubing, and suction power.
RESULTS
Sixty portable airway suction devices were resulted, 31 of which met inclusion criteria - 11 manually powered devices and 20 battery-operated devices. One type of manual suction pump was a bag-like design with a squeezable suction pump that was extremely lightweight but had limited suction capabilities (vacuum pressure of 100mmHg). Another type of manual suction pump had a trigger-like design which is pulled back to create suction with a firm collection canister that had increased suction capabilities (vacuum pressures of 188-600mmHg), though still less than the battery operated, and was slightly heavier (0.23-0.458kg). Battery-operated devices had increased suction capabilities and were easier to use, but they were larger and weighed more (1.18-11.0kg).
CONCLUSION
Future research should work to lighten and debulk battery-operated suction devices with high suction performance.

BACKGROUND
Extracellular recording of nerve activities using suction electrodes is an easy yet powerful tool in characterizing neural activities in physiology and pathological conditions. The key factors that determine the quality of suction electrode recordings have not been fully investigated. New Methods: Here, we proposed a biophysical model to study the mechanisms underlying suction technology for axon recording. The model focuses on the interpretation of the recorded single neuron activity based on the location of the electrode, the integrity of the recorded tissue, and the tightness of the suction. To directly test these model predictions, we applied two channel recordings from the nerves in Aplysia californica, and analyzed the shape of the extracellularly recorded single neuron activity under various conditions.
RESULTS
We found that both the recording site and the integrity of the neural tissue impact the shape of the action potentials traveling along the axon. In practice, the tightness of the suction is the key parameter for high-quality recordings using a suction electrode. Comparison with Existing Methods: Experimental protocols that can improve precise positioning of the electrode tip to the target nerve, avoid tissue damage, enhance suction force, and maintain tightness are essential for high-quality suction recording from axons. Current methods have not emphasized on achieving and maintaining of the suction pressure during experimentation, and have sometimes ignored the impact of suction electrode position or tissue damage to the quality of the recorded neural signal.
CONCLUSIONS
A combined theoretical analysis and experimental approach is essential in improving neural recording technology. The work provides theoretical and practical guidelines to improve suction technology. This work also provides valuable insights to the improvement of several other extracellular recording technology in laboratory research or clinical settings.

Meta-Analysis Review
BACKGROUND
Acute appendicitis is one of the most frequent abdominal surgical emergencies. Intra-abdominal abscess is a frequent post-operative complication. The aim of this meta-analysis was to compare peritoneal irrigation and suction versus suction only when performing appendectomy for complicated appendicitis.
METHODS
According to PRISMA guidelines, a systematic review was conducted and registered into the Prospero register (CRD42020186848). The risk of bias was defined to be from low to moderate.
RESULTS
Seventeen studies (9 RCTs and 8 CCTs) were selected, including 5315 patients. There was no statistical significance in post-operative intra-abdominal abscess in open (RR 1.27, 95% CI 0.75-2.15; I = 74%) and laparoscopic group (RR 1.51, 95% CI 0.73-3.13; I = 83%). No statistical significance in reoperation rate in open (RR 1.27, 95% CI 0.04-2.49; I = 18%) and laparoscopic group (RR 1.42, 95% CI 0.64-2.49; I = 18%). In both open and laparoscopic groups, operative time was lower in the suction group (RR 7.13, 95% CI 3.14-11.12); no statistical significance was found for hospital stay (MD - 0.39, 95% CI - 1.07 to 0.30; I = 91%) and the rate of wound infection (MD 1.16, 95% CI 0.56-2.38; I = 71%).
CONCLUSIONS
This systematic review has failed to demonstrate the statistical superiority of employing intra-operative peritoneal irrigation and suction over suction-only to reduce the rate of post-operative complications after appendectomy, but all the articles report clinical superiority in terms of post-operative abscess, wound infection and operative times in suction-only group.

BACKGROUND
Thoracentesis using suction is perceived to have increased risk of complications, including pneumothorax and re-expansion pulmonary oedema (REPO). Current guidelines recommend limiting drainage to 1.5 L to avoid REPO. Our purpose was to examine the incidence of complications with symptom-limited drainage of pleural fluid using suction and identify risk factors for REPO.
METHODS
A retrospective cohort study of all adult patients who underwent symptom-limited thoracentesis using suction at our institution between January 1, 2004 and August 31, 2018 was performed, and a total of 10 344 thoracenteses were included.
RESULTS
Pleural fluid ≥1.5 L was removed in 19% of the procedures. Thoracentesis was stopped due to chest discomfort (39%), complete drainage of fluid (37%) and persistent cough (13%). Pneumothorax based on chest radiography was detected in 3.98%, but only 0.28% required intervention. The incidence of REPO was 0.08%. The incidence of REPO increased with Eastern Cooperative Oncology Group performance status (ECOG PS) ≥3 compounded with ≥1.5 L (0.04-0.54%; 95% CI 0.13-2.06 L). Thoracentesis in those with ipsilateral mediastinal shift did not increase complications, but less fluid was removed (p<0.01).
CONCLUSIONS
Symptom-limited thoracentesis using suction is safe even with large volumes. Pneumothorax requiring intervention and REPO are both rare. There were no increased procedural complications in those with ipsilateral mediastinal shift. REPO increased with poor ECOG PS and drainage ≥1.5 L. Symptom-limited drainage using suction without pleural manometry is safe.

Airway clearance refers to the clearing of any airway blockage caused due to foreign objects such as mud, gravel, and biomaterials such as blood, vomit, or teeth fragments using the technology of choice, portable suction devices. Currently available devices are either too heavy and bulky to be carried, or insufficiently powered to be useful despite being in accordance with the ISO 10079-1 standards. When applied to portable suction, the design and testing standards lack clinical relevancy, which is evidenced by how available portable suction devices are sparingly used in pre-hospital situations. Lack of clinical relevancy despite being in accordance with design/manufacturing standards arise due to little if any collaboration between those developing clinical standards and the bodies that maintain design and manufacturing standards. An updated set of standards is required that accurately reflects evidence-based requirements and specifications, which should promote valid, rational, and relevant engineering designs and manufacturing standards in consideration of the unique scenarios facing prehospital casualty care. This paper aims to critically review the existing standards for portable suction devices and propose modifications based on the evidence and requirements, especially for civilian prehospital and combat casualty care situations.

Review
PURPOSE
The considered benefit of surgical drain use after spinal surgery is to prevent local accumulation of a haematoma by decompressing the closed space in the approach of the surgical site. In this context, the aim of the present systematic review was to prove the benefit of the routine use of closed-suction drains.
METHODS
We conducted a comprehensive systematic review of the literature according to the Preferred reporting items for systematic reviews and meta-analyses (PRISMA) checklist and algorithm.
RESULTS
Following the literature search, 401 potentially eligible investigations were identified. Eventually, a total of 24 studies with 8579 participants were included. Negative suction drainage led to a significantly higher volume of drainage fluid. Drainage duration longer than 72 h may be associated with a higher incidence of Surgical side infections (SSI); however, accompanying antibiotic treatment is unnecessary. Regarding postoperative haematoma and neurological complications, no evidence exists concerning their prevention. Hospital stay length and related costs may be elevated in patients with drainage but appear to depend on surgery type.
CONCLUSIONS
With regard to the existing literature, the use of closed-suction drainage in elective thoracolumbar spinal surgery is not associated with any proven benefit for patients and cannot decrease postoperative complications.

Surgery, by nature, involves blood loss. Thus, suction plays an important role in ensuring a clean operating view and ease of access. In ophthalmology, there is a void for an efficient and flexible suction apparatus that is yet to be filled. Our innovation, the Eyespirator, is made using recycled or inexpensive parts, is easy to assemble, and can serve as a cost-effective alternative to the current apparatus under use. It helps to overcome the difficulties caused by large instruments and non-pliable suction tips, unregulated generation of vacuum, and high pressures generated causing trauma to the delicate structures, and can prove to be of immense use in fields such as ophthalmology where the small surgical field is a big challenge. It creates a vacuum by using a simple water pump and is regulated by a foot pedal. This can be deployed even in rural settings, and small modifications can allow its usage in a wide variety of surgical fields.

Meta-Analysis Review
INTRODUCTION
The role of closed suction drainage during elective total joint arthroplasty is still unclear. The present study compared the use of closed suction drains to no drainage for elective total knee arthroplasty (TKA) and in total hip arthroplasty (THA) through a meta-analysis of randomized clinical trials (RCTs).
METHODS
Following the PRISMA guidelines, a meta-analysis of randomized controlled trials identified in December 2021. All randomized clinical trials comparing the use of closed suction drains to no drainage for elective THA or TKA were considered.
RESULTS
Twenty-five RCTs were included in the final analysis. 49% (1722 of 3505) of patients received no-drainage, and 51% (1783 of 3505) received closed suction drainage. There was no evidence of a statistically significant evidence between the two groups in occurrence of postoperative infections (P = 0.4), mean total postoperative hemoglobin (P = 0.2) or length of hospital stay (P = 0.1). The no-drainage group showed a lower rate of blood transfusion (P < 0.0001).
CONCLUSION
There is no evidence to support the routine use of closed suction drainage in THA or TKA patients.
