Brief summary

A systematic review of 84 cases of airway compromise following carotid endarterectomy found that external neck findings correlate poorly with internal distortion, laryngeal edema is frequently more severe than anticipated, and prompt hematoma evacuation improves airway management success.

What NurseJet pulled from the source

Synthesizing 11 studies detailing 84 patients, the review found that life-threatening airway compromise can develop rapidly from neck hematoma and severe laryngeal edema. Bedside wound exploration under local anesthesia often avoided invasive airway rescue, awake intubation had fewer complications than asleep induction, and emergency surgical airway access should not be delayed by repeated failed intubations.

Why this matters for nurses

Nurses in PACU, Neuro ICU, and post-surgical units are the first line of defense in detecting airway compromise after carotid surgery. Because subtle external swelling can mask critical supraglottic closure, immediate recognition and preparedness for bedside hematoma decompression are life-saving.

Bedside takeaway

Visible neck swelling after carotid endarterectomy severely underestimates internal airway edema; escalate expanding swelling immediately and ensure bedside decompression readiness.

Key takeaways

Clinical signs and visible external neck swelling correlate poorly with internal anatomical distortion, and laryngeal edema is typically more severe than expected.
Prompt hematoma evacuation improved the success rate of airway management without associated morbidity or mortality, and surgical decompression under local anesthesia may avoid difficult re-intubation.
Awake tracheal intubation was associated with fewer complications than asleep intubation, and front-of-neck access should not be delayed by repeated intubation attempts.

Practice implications

Routinely inspect neck dressings, measure neck circumference or tracheal alignment if indicated, and watch for stridor, restlessness, or respiratory effort. Keep a bedside suture-removal tray and emergency airway equipment immediately accessible, escalate expanding neck fullness immediately, and avoid sedating struggling patients.

Limitations & cautions

The evidence base was limited to 11 retrospective studies, case series, and case reports totaling 84 patients. Observational data may reflect reporting bias toward severe presentations, and prospective randomized comparisons of emergency airway techniques are not feasible in this setting.

Neurosurgical review (PubMed)Oct 17, 2026Systematic Review

A systematic review and meta-analysis of 14 studies comprising 7,981 patients found extending single-agent antibiotic prophylaxis beyond one day did not reduce postoperative meningitis after endoscopic endonasal skull base surgery, whereas intraoperative CSF leak significantly increased infection risk.

Postoperative meningitis is an uncommon but severe complication following endoscopic endonasal skull base surgery (EESBS). While perioperative antimicrobial prophylaxis is universally administered, the required duration remains controversial, frequently leading to prolonged, non-evidence-based antibiotic courses. Following PRISMA guidelines, researchers meta-analyzed 14 studies covering 7,981 patients receiving single-agent antibiotic prophylaxis categorized as ultra-short (≤1 day), short (1–3 days), or long (>3 days). The pooled incidence of postoperative meningitis across all cohorts was 1.38% (95% CI: 0.92%–2.08%; I² = 65.8%). Subgroup analysis showed comparable meningitis rates across duration cohorts: 1.24% for ultra-short prophylaxis (95% CI: 0.66%–2.32%), 1.20% for short prophylaxis (95% CI: 0.38%–3.70%), and 2.12% for long prophylaxis (95% CI: 0.82%–5.36%), with no statistically significant difference (p = 0.764). Meta-regression confirmed prophylaxis duration was not associated with meningitis (p = 0.487). Instead, higher study-level prevalence of intraoperative cerebrospinal fluid (CSF) leakage was significantly associated with increased meningitis rates (β = 0.0389 per percentage point; p = 0.010).

Key takeaways

Meta-analysis evaluated 14 studies including 7,981 patients undergoing endoscopic endonasal skull base surgery.
Overall postoperative meningitis incidence was 1.38% (95% CI: 0.92%–2.08%).
Meningitis rates did not differ between ultra-short ≤1 day (1.24%), short 1–3 days (1.20%), or long >3 days (2.12%) antibiotic regimens (p = 0.764).
Intraoperative CSF leakage was a significant driver of postoperative meningitis (p = 0.010), while prolonged antibiotic coverage conferred no protective benefit.

Why this matters on shift

Infection preventionists and perioperative surgical nurses champion antimicrobial stewardship by stopping surgical prophylaxis within 24 hours post-procedure. This large-scale evidence confirms that extending prophylactic antibiotics beyond 24 hours does not prevent central nervous system infections in skull base surgery and reinforces focusing post-op surveillance on intraoperative CSF leak status rather than extended antibiotic exposure.

Bedside takeaway

In 7,981 skull base surgeries, postoperative meningitis incidence was 1.38% and did not differ between ≤1 day (1.24%) and >3 days (2.12%) of antibiotics, while CSF leak was the primary infection risk.

Nursing implications

Support timely discontinuation of perioperative antibiotics within 24 hours post-op in accordance with national surgical infection prevention guidelines, maintain high clinical vigilance for signs of CSF rhinorrhea, headache, nuchal rigidity, and fever, and ensure rapid diagnostic escalation if CSF drainage is suspected.

Limitations & cautions

Included cohorts were retrospective observational studies with moderate heterogeneity (I² = 65.8%); specific antibiotic choices and dosing regimens varied across surgical centers.

Trauma, violence & abuse (PubMed)Oct 17, 2026Systematic Review

A systematic review and meta-analysis of 20 emergency department studies encompassing 7,498 women found intimate partner violence was associated with a three-fold increased risk of suicide attempt, with psychological violence showing a stronger association than physical violence.

Women experiencing intimate partner violence (IPV) and acute suicidality frequently seek medical evaluation in emergency departments (EDs), but the intersection between these two acute presentations is often overlooked during fast-paced triage. This systematic review, meta-analysis, and narrative synthesis synthesized 20 ED-based studies comprising 7,498 women across three global databases. Investigators used random-effects models and evaluated study quality with the Joanna Briggs Institute (JBI) checklist. Overall, 22% (95% CI: 11%–36%) of women presenting to the ED for suicide-related care had a history of physical IPV, while 13% (95% CI: 8%–18%) of women with known IPV histories reported active suicidality. A history of IPV was associated with a three-fold increase in the risk of suicide attempt (risk ratio [RR] 3.00; 95% CI: 1.39–6.47). Notably, psychological IPV demonstrated a stronger association with suicide risk (RR 3.23; 95% CI: 1.68–6.19) than physical IPV alone (RR 2.00; 95% CI: 1.26–3.17).

Key takeaways

Systematic review synthesized 20 emergency department studies encompassing 7,498 women.
Nearly 1 in 4 women (22%; 95% CI: 11%–36%) presenting to the ED with suicidality had experienced physical IPV.
IPV was associated with a three-fold higher risk of suicide attempt (RR 3.00; 95% CI: 1.39–6.47).
Psychological IPV showed a higher risk ratio for suicide attempts (RR 3.23; 95% CI: 1.68–6.19) than physical IPV (RR 2.00; 95% CI: 1.26–3.17).

Why this matters on shift

Emergency nurses are the primary healthcare professionals conducting universal triage, suicide risk screening (e.g., C-SSRS), and domestic violence assessments. Recognizing that nearly one-quarter of suicidal female presentations co-occur with IPV—and that non-physical, psychological abuse carries an even higher relative risk for suicide attempt—demands that ED nursing assessments integrate trauma-informed safety planning rather than treating suicidality and relationship violence in isolation.

Bedside takeaway

In an ED meta-analysis of 7,498 women, intimate partner violence tripled suicide attempt risk (RR 3.00), with psychological IPV (RR 3.23) linked more strongly than physical IPV (RR 2.00).

Nursing implications

Conduct routine IPV and suicide screenings privately away from companions or visitors, assess for emotional and psychological coercion even when physical injury is absent, and connect patients showing combined risk immediately to hospital social work, victim advocacy, and safe crisis intervention pathways.

Limitations & cautions

High between-study heterogeneity across meta-analytic models (I² > 75%); high risk of bias identified in half of the included primary studies; relied largely on cross-sectional self-reported survey measures.

Anesthesia and analgesia (PubMed)Oct 16, 2026Systematic Review

A meta-analysis of 25 randomized controlled trials with 3,344 surgical patients found perioperative ketamine and esketamine were associated with reduced postoperative delirium between days 2 and 7, but significantly increased postoperative dizziness.

Postoperative delirium (POD) is a common, distressing complication in older surgical patients, yet effective pharmacologic prevention options remain limited. This systematic review and meta-analysis of 25 randomized controlled trials (RCTs) involving 3,344 patients evaluated perioperative administration of ketamine (9 trials) and esketamine (16 trials) compared to placebo or standard care. Both agents were associated with reduced POD incidence (ketamine: risk ratio [RR] 0.69; 95% CI, 0.49–0.98; P = .04; esketamine: RR 0.58; 95% CI, 0.36–0.95; P = .03). Risk reductions were most evident with higher-dose regimens (single bolus: ketamine >0.5 mg/kg or esketamine >0.25 mg/kg; cumulative dose: ketamine >1.0 mg/kg or esketamine >0.5 mg/kg), bolus-plus-infusion administration, and in major surgical procedures. However, the preventative association was present only when delirium was assessed between postoperative days 2 and 7, not within the first 24 hours. Furthermore, ketamine/esketamine significantly increased the risk of postoperative dizziness (RR 1.45; 95% CI, 1.14–1.84; P = .002). Trial sequential analysis indicated that total evidence remains inconclusive due to insufficient overall sample size.

Key takeaways

Meta-analysis analyzed 25 RCTs with 3,344 patients receiving perioperative ketamine (9 trials) or esketamine (16 trials).
Both agents were associated with lower POD incidence versus control: ketamine RR 0.69 (P = .04) and esketamine RR 0.58 (P = .03).
Delirium reduction was apparent at postoperative days 2 to 7, but not during the initial 24 hours.
Dizziness risk was significantly elevated in treated patients (RR 1.45; 95% CI, 1.14–1.84; P = .002), and trial sequential analysis found cumulative sample size insufficient to draw definitive conclusions.

Why this matters on shift

Surgical and post-anesthesia nurses monitor older adults recovering from general anesthesia for confusion, agitation, and fall risk. While ketamine and esketamine show potential neurocognitive protective signals beyond day 1, their heightened dizziness profile increases post-op balance instability, requiring cautious bedside mobility precautions rather than unreserved clinical adoption.

Bedside takeaway

In a meta-analysis of 25 RCTs (3,344 patients), perioperative ketamine (RR 0.69) and esketamine (RR 0.58) reduced delirium at days 2–7 but significantly increased dizziness (RR 1.45).

Nursing implications

Screen surgical patients systematically for emergence and delayed delirium using validated tools (such as CAM or CAM-ICU) through postoperative day 7, implement strict fall and dizziness precautions when ketamine derivatives are administered, and avoid assuming early alertness guarantees absence of delayed delirium.

Limitations & cautions

Trial sequential analysis confirmed current evidence remains inconclusive due to inadequate total information size; dizziness was increased (RR 1.45); high heterogeneity in surgical populations and anesthesia protocols.
