Clinical Research of Early Hyperbaric Oxygen Therapy on Patients with Hypertensive Cerebral Hemorrhage After Craniotomy

Research progress of postoperative delirium in neurosurgery

Delirium is a transient and acute syndrome of encephalopathy, characterized by disturbances in consciousness, orientation, cognition, perception, and emotional regulation, often accompanied by hallucinations, illusions, psychomotor agitation, and restlessness. Postoperative delirium (POD), a common complication particularly in elderly patients, significantly impacts recovery by prolonging mechanical ventilation, neurosurgical intensive care unit stays, and overall hospitalization durations, while severely diminishing patients' quality of life after discharge. Despite its prevalence, POD remains underrecognized in clinical practice, with significant gaps in its diagnosis and management. This review explores the definition, diagnostic criteria, underlying pathogenesis, and associated risk factors of POD in neurosurgical patients, aiming to offer valuable insights for improving clinical diagnosis and therapeutic strategies.

Value of inflammatory mediator profiles and procalcitonin in predicting postoperative infection in patients with hypertensive cerebral hemorrhage

BACKGROUND

Hypertensive cerebral hemorrhage (HICH) is a common clinical cerebrovascular disease and one of the most serious complications of hypertension. Early warning of the occurrence of infection during treatment and timely anti-infective treatment are of great significance for the early prevention and treatment of postoperative infection in patients with HICH. Changes in the levels of inflammatory mediators, which are closely related to the occurrence and development of postoperative infection, and procalcitonin (PCT), which is a sensitive indicator for diagnosing bacterial infections, are widely used in clinical practice.

AIM

To explore the application value of inflammatory mediator profiles and PCT in predicting postoperative infection in patients with HICH.

METHODS

A total of 271 patients who underwent HICH surgery at our hospital between March 2019 and March 2021 were selected and divided into the infection (n = 80) and non-infection (n = 191) groups according to whether postoperative infection occurred. The postoperative infection status and etiological characteristics of the infective pathogens in the infection group were analyzed. Changes in inflammatory mediator profile indices and PCT levels were compared between the two groups, pre- and postoperatively.

RESULTS

A total of 109 strains of pathogenic bacteria were detected in the infection group, including 67 strains (61.47%) of gram-negative bacteria, 32 strains (29.36%) of gram-positive bacteria, and 10 strains (9.17%) of fungi. The main infection site of the patients in the infection group was the respiratory system (63.75%). Preoperative interleukin (IL)-4, IL-6, IL-10, tumor necrosis factor-α, interferon-γ, and PCT levels were higher in the infection group than in the non-infection group (P < 0.05), and there were no significant differences in the IL-2 Levels between the two groups (P > 0.05). The inflammatory mediator profile indices and PCT levels were higher in the two groups of patients on the first postoperative day than preoperatively (P < 0.05), and were higher than those in the non-infection group (P < 0.05). Logistic regression analysis showed that preoperative IL-6 and PCT levels correlated with postoperative infection (P < 0.05). Operating characteristic curve analysis results showed that the area under the curve (AUC) values of preoperative IL-6 and PCT levels in predicting postoperative infection in patients with HICH were 0.755 and 0.824, respectively. The AUC value of joint detection was 0.866, which was significantly higher than that of the single index (P < 0.05).

CONCLUSION

Preoperative IL-6 and PCT levels are correlated with postoperative infection in patients with HICH. Their detection is clinically significant for early identification of patients at high risk for postoperative infection.

The Effect of Hemoglobin Concentration on Hyperbaric Oxygen and Non-hyperbaric Oxygen in the Treatment of Hypertensive Intracerebral Hemorrhage After Operation at the High Altitude

Background

The prognosis of hypertensive intracerebral hemorrhage (HICH) is poor at high altitudes. The objective of this study was to explore whether hyperbaric oxygen (HBO) can improve the results of computed tomography perfusion (CTP) imaging and the neurological function of patients with HICH, and influence the hemoglobin concentration.

Method

The patients with HICH were treated with puncture and drainage. Twenty-one patients (51.22% of 41 patients in total) were treated with HBO after the operation, and the other patients received conventional treatment. CTP was performed twice, and all indices were measured. Scatter plots were used to determine the effect of hemoglobin concentration on CTP imaging. Receiver operating characteristic (ROC) curves were plotted to analyze the effects of hemoglobin concentration and hematoma volume on recovery results. The patients were followed up for 6 months.

Results

Forty-one patients with HICH were treated with puncture and drainage. In total, 21 were treated with HBO after the operation, and 20 received conventional treatment as the control group. No significant differences in the CBV and CBF values of the two groups were noted before treatment. After 10 days, the values of CBV and CBF in the HBO group were significantly higher than those in the control group. A scatter diagram showed there was no significant in the HBO group, but significant correlation for the CBV and CBF values in the control group’s hematoma center and margin. The ROC curves showed that hematoma volume had an influence on prognosis of the control group. The Glasgow Coma Scale (GOS) scores of the HBO group were significantly higher than those of the control group (p &lt; 0.05).

Conclusions

HBO therapy can improve the postoperative CBV and CBF values of patients with HICH and ameliorate their prognoses. There was no significant correlation between HBO group and hemoglobin concentration on admission.

Analysis of the Therapeutic Effect and Prognostic Factors of 126 Patients With Hypertensive Cerebral Hemorrhage Treated by Soft-Channel Minimally Invasive Puncture and Drainage

Background

Surgery is the main method for the clinical treatment of hypertensive cerebral hemorrhage. Traditional craniotomy faces the disadvantages of the long operation time, easy to cause secondary injury to patients during the operation, and prone to infection after the operation, which is not conducive to the rehabilitation of patients. At present, it is urgent to find a surgical scheme, which can clear hematoma in time, protect brain tissue, and effectively reduce surgical trauma in the clinic.

Materials and Methods

The case database of our hospital was consulted, and the clinical data of patients with hypertensive intracerebral hemorrhage (HICH) treated with soft channel minimally invasive puncture and drainage from February 2018 to October 2021 were retrospectively analyzed. Patients were evaluated for efficacy, and the changes in serum C-reactive protein (CRP), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), homocysteine (Hcy), endothelin (ET), and vasopressin (AVP) levels before surgery, 3 days after surgery, and 7 days after surgery were analyzed. Clinical data were collected and Logistic regression was used to analyze the prognostic factors.

Results

Finally, according to the inclusion and exclusion criteria, 126 patients were selected as the research object. Among them, there were 24 cases (19.05%) of recovery, 47 cases (37.30%) of markedly effective, 34 cases (26.98%) of effective, 11 cases (8.73%) of ineffective, and 10 cases (7.94%) of death. The total effective rate was 83.33%. The hematoma was basically removed in 116 cases (92.06%). The average evacuation time of hematoma was (7.82 ± 1.63) days. Post-operative intracranial infection occurred in 2 cases (1.59%) and post-operative rebleeding occurred in 5 cases (3.97%). The average hospital stay was (34.16 ± 16.59) days. Serum CRP, TNF-α, IL-6, Hcy, ET, and AVP levels of all patients on the third and seventh days after surgery were lower than those before surgery, and those on the seventh day after surgery were lower than those on the third day after surgery (p < 0.05). The differences in pre-operative Glasgow Coma Scale (GCS) score, bleeding volume, ventricular rupture, complicated cerebral hernia, and attack time to surgery between the good prognosis group and the bad prognosis group were statistically significant (p < 0.05). Pre-operative GCS score, bleeding volume, ventricular rupture, complicated cerebral hernia, and onset time to surgery were all independent factors that affect the prognosis of patients (p < 0.05).

Conclusion

Soft-channel minimally invasive puncture and drainage treatment of HICH has a significant effect, which is conducive to the complete removal of hematoma, reducing hospitalization time, while adjusting the balance and stability of various cytokines, and improving patient prognosis. Pre-operative GCS score, bleeding volume, rupture into the ventricle, complicated cerebral hernia, and time from onset to operation are all independent factors that affect the prognosis of patients.
