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.

Primary and secondary postoperative hemorrhage in pediatric tonsillectomy

Tonsillectomy is the most common procedure for treatment of pediatric recurrent acute tonsillitis and tonsillar enlargement that contributes to obstructive sleep apnea hypopnea syndrome.Postoperative hemorrhage of tonsillectomy is a lifethreatening complication.AIM To identify the risk factors that may contribute to primary and secondary postoperative hemorrhage in pediatric tonsillectomy.METHODS The clinical data from 5015 children,3443 males and 1572 females,aged 1.92-17.08 years,with recurrent tonsillitis and/or tonsil hypertrophy who underwent tonsillectomy in our hospital from January 2009 to December 2018 were retrospectively collected.The variables including sex,age,time of onset,diagnosis,method of tonsillectomy,experience of surgeon,time when the surgery started and monthly average air temperature were abstracted.The patients with postoperative hemorrhage were classied into two groups,the primary bleeding group and the secondary bleeding group,and their characteristics were compared with those of the nonbleeding group separately.Statistical analysis was performed by chi-square test with SPSS 20.RESULTS Ninety-two patients had post-tonsillectomy hemorrhage,and the incidence rate of post-tonsillectomy hemorrhage was 1.83%.The mean age was 5.75 years.Cases of primary hemorrhage accounted for approximately 33.70%(31/92),and cases of secondary hemorrhage occurred in 66.30%(61/92).The rate of reoperation for bleeding was 0.92%,and the rate of rehospitalization for bleeding was 0.88%in all patients.Multiple hemostasis surgery was performed in 6.52%(3/46)of patients.The method of tonsillectomy(coblation tonsillectomy)and experience of the surgeon(junior surgeon with less than 5 years of experience)were significantly associated with primary hemorrhage(χ^(2)=5.830,P=0.016,χ^(2)=6.621,P=0.010,respectively).Age(over 6 years old)and time of onset(more than a 1-year history)were significantly associated with secondary hemorrhage(χ^(2)=15.242,P=0.000,χ^(2)=4.293,P=0.038,respectively).There was no signicant difference in sex,diagnosis,time when the surgery started or monthly average air temperature.There was a signicant difference in the intervention measures between the primary bleeding group and the secondary bleeding group(χ^(2)=10.947,P=0.001).The lower pole and middle portion were the common bleeding sites,followed by the upper pole and palatoglossal arch.CONCLUSION The incidence rate of post-tonsillectomy hemorrhage is low.Coblation tonsillectomy and less than 5 years’experience of surgeon contribute to the tendency for primary hemorrhage.Age and time of onset are responsible for secondary hemorrhage.

Lung imaging characteristics in a patient infected with Elizabethkingia miricola following cerebral hemorrhage surgery: A case report

BACKGROUND Elizabethkingia miricola is a non-fermenting gram-negative bacterium,which was first isolated from the condensate of the Russian peace space station in 2003.Most studies on this bacterium have been carried out in the laboratory,and clinical case studies are rare.To date,a total of 6 clinical cases have been reported worldwide.CASE SUMMARY We present the first case of postoperative pulmonary infection in a patient with intracerebral hemorrhage due to Elizabethkingia miricola.The imaging character-istics of pulmonary infection were identified and the formulation and selection of the clinical treatment plan for this patient are discussed.CONCLUSION Elizabethkingia miricola infection is rare.When pulmonary infection occurs,computed tomography imaging may show diffuse distribution of a ground glass density shadow in both lungs,the air containing bronchial sign in local areas,thickening of bronchial vascular bundle,and pleural effusion.

Transarterial embolization for massive gastrointestinal hemorrhage following abdominal surgery

AIM:To evaluate the clinical results of angiography and embolization for massive gastrointestinal hemorrhage after abdominal surgery.METHODS:This retrospective study included 26 patients with postoperative hemorrhage after abdominal surgery. All patients underwent emergency transarterial angiography,and 21 patients underwent emergency embolization. We retrospectively analyzed the angiographic features and the clinical outcomes of transcatheter arterial embolization.RESULTS:Angiography showed that a discrete bleeding focus was detected in 21(81%) of 26 patients.Positive angiographic findings included extravasations of contrast medium(n = 9),pseudoaneurysms(n =9),and fusiform aneurysms(n = 3). Transarterial embolization was technically successful in 21(95%) of 22patients. Clinical success was achieved in 18(82%) of 22 patients. No postembolization complications were observed. Three patients died of rebleeding.CONCLUSION:The positive rate of angiographic findings in 26 patients with postoperative gastrointestinal hemorrhage was 81%. Transcatheter arterial embolization seems to be an effective and safe method in the management of postoperative gastrointestinal hemorrhage.

Risk factors and managements of hemorrhage associated with pancreatic fistula after pancreaticoduodenectomy

BACKGROUND: Post-pancreaticoduodenectomy pancreatic fistula associated hemorrhage (PPFH) is one of the leading lethal complications. Our study was to analyze the risk factors and managements of hemorrhage associated with pancreatic fistula after pancreaticoduodenectomy, and to evaluate treatment options. METHOD: We analyzed 445 patients who underwent pancreaticoduodenectomy or pylorus-preserving pancreaticoduodenectomy and evaluated the relevance between clinical data and PPFH. RESULTS: The incidence of postoperative pancreatic fistula (POPF) was 27.42% (122/445), and the incidence of PPFH was 4.49% (20/445). Among the 20 patients with PPFH, 7 died and 13 were cured. Interventional angiographic therapy was performed for 10 patients and 5 were successfully treated. Relaparotomy was performed for 5 patients and 2 were successfully cured. Univariate logistic regression analysis indicated that several risk factors were related to PPFH: the nature of tumor (carcinoid/low-grade or high-grade malignancy), preoperative day 1. serum prealbumin, preoperative day 1 total bilirubin (TBIL), operative time, blood loss in the operation, operative method (vascular resection and revascularization), postoperative day 3 TBIL, biliary fistula, and the grade of POPF. The multivariate stepwise logistic regression analysis demonstrated that the nature of tumor and the grade of POPF were independently risk factors of PPFH. Receiver operating characteristic curve indicated that preoperative day 1 serum prealbumin level <173 mg/L and postoperative day 3 TBIL level.1.68.tmol/L were the risk factors of PPFH. CONCLUSIONS; The risk of PPFH was found to be increased with high potential malignancy and high grade of POPE Angiography-embolization is one of the major and effective therapies for PPFH. Extraluminal-intraluminal PPFH is more serious and needs more aggressive treatments.

Postoperative bleeding in patients on antithrombotic therapy after gastric endoscopic submucosal dissection

To investigated the relationship between postoperative bleeding following gastric endoscopic submucosal dissection (ESD) and individual antithrombotic agents. METHODSA total of 2488 gastric neoplasms in 2148 consecutive patients treated between May 2001 and June 2016 were studied. The antithrombotic agents were categorized into antiplatelet agents, anticoagulants, and other antithrombotic agents, and we included combination therapies [e.g., dual antiplatelet therapy (DAPT)]. The risk factors associated with post-ESD bleeding, namely, antithrombotic agents overall, individual antithrombotic agents, withdrawal or continuation of antithrombotic agents, and bleeding onset period (during the first six days or thereafter), were analyzed using univariate and multivariate analyses. RESULTSThe en bloc resection and complete curative resection rates were 99.2% and 91.9%, respectively. Postoperative bleeding occurred in 5.1% cases. Bleeding occurred in 10.3% of the patients administered antithrombotic agents. Being male (P = 0.007), specimen size (P < 0.001), and antithrombotic agent used (P < 0.001) were independent risk factors for postoperative bleeding. Heparin bridging therapy (HBT) (P = 0.002) and DAPT/multidrug combinations (P < 0.001) were independent risk factors associated with postoperative bleeding. The bleeding rate of the antithrombotic agent continuation group was significantly higher than that of the withdrawal group (P < 0.01). Bleeding within postoperative day (POD) 6 was significantly higher in warfarin (P = 0.015), and bleeding after POD 7 was significantly higher in DAPT/multidrug combinations (P = 0.007). No thromboembolic events were reported. CONCLUSIONWe must closely monitor patients administered HBT and DAPT/multidrug combinations after gastric ESD, particularly those administered multidrug combinations after discharge.

Objective:This study aimed to evaluate the efficacy and safety of selective arterial embolization for hemorrhage after renal surgery and to summarize the clinical experience.Materials and methods:A total of 9 patients underwent arterial embolization after partial nephrectomy from 2010 to 2018.Results:Technical success was achieved in all patients;however,3 patients underwent a secondary arterial embolization because of short-term re-hemorrhage or the co-occurrence of accessory renal arterial hemorrhage.No serious complications occurred during the follow-up.Conclusions:Superselective arterial embolization is an effective and minimally invasive treatment for hemorrhage after partial nephrectomy.To improve the success rate of surgery,attention should be paid to the evaluation of accessory renal arteries and the management of suspected bleeding arteries.

Progress in Analgesic-Sedative Treatment in Perioperative Period of Hypertensive Intracerebral Hemorrhage

Hypertensive intracerebral hemorrhage (HICH) refers to intra cerebral hemorrhage at basal ganglia, thalamus, ventricle, cerebellum and brainstem in patients with history of explicit hypertension disease, excluding secondary cerebral hemorrhage caused by trauma, vascular structural disorders, coagulation disorders, hematologic diseases, systematic diseases and neoplastic diseases. HICH is characteristic of high morbidity, fatality rate, disability rate and recurrence rate. HICH is the most common type of spontaneous cerebral hemorrhage and various surgical interventions are one of the major treatments for HICH. Surgical treatment is to eliminate hematoma, relieve oppression of hematoma on surrounding brain tissues, lower intracranial pressure and alleviate secondary brain tissue damages, thus enabling to decrease fatality rate of patients and improve the long-term quality of life. Patients with HICH often may have different degrees of coma, pains, dysphoria, anxiety and delirium in the postoperative period. After central pivot was damaged, the sympathetic central excitability spreading is strengthened in the state of cortical inhibition, which also might be accompanied by paroxysmal sympathetic hyperexcitation syndrome to strengthen disease conditions of patients and thereby influence subsequent treatment. Several professional guidelines all recommend analgesic-sedative treatment as an important component of ICU therapy. However, it lacks support by large sample sized clinical research results of analgesic-sedative treatment of HICH in the postoperative period. This study analyzed literature concerning analgesic-sedative treatment of HICH in the postoperative period in recent years, aiming to guide specific clinical implementation.

Objective:To summarize the experience without hemorrhage after PPH of 218 patients with mixed hemorrhoid.Methods:PPH(Procedure for prolapse and hemorrhoids)was performed routinely.During operation,it is paid attention that the hemorrhoid artery should be completely mutilated,the anastomat should be squeezed before and after the anastomosis,the anastomosis should be carefully examined,the hemostasis should be completely performed,and relevant hemostasis measures should be taken after the operation.Results:None of the 218 patients had postoperative hemorrhage.Conclusion:Relevant measures can be taken after operation to prevent the occurrence of postoperative hemorrhage.

Time Course of Postoperative Complications in Low-Risk Women after Planned Cesarean Section

Objectives: Length of hospital stay after cesarean section is today much shorter than previously, and a stay of only 1 day is used in many departments. However, complications requiring immediate treatment must be diagnosed before leaving hospital. We assessed the time interval from planned cesarean section to diagnosis of major complications in low-risk women to estimate a safe time of discharge. Methods: We performed a retrospective observational study among 5633 women undergoing planned cesarean section from 2001-2017 at Aarhus University Hospital, Denmark. The inclusion criterion was postoperative complication graded as Clavien-Dindo ≥ II. Exclusion criteria were preoperative comorbidity or problems during surgery indicative of need for prolonged stay. Time from cesarean section to suspicion of a postoperative complication was the primary endpoint. Results: The study population consisted of 116 women with unexpected postoperative complications, 47 classified as Clavien-Dindo II and 69 as Clavien-Dindo III-IV. In 63 of the 116, the diagnoses were suspected within 24 hours (Clavien-Dindo II: 25, Clavien-Dindo III-IV: 38). These included all cases of relaparotomy and uterine atony with immediate need of medical treatment. Acute colonic pseudo-obstruction was diagnosed within 2 days, while other complications were suspected and treated 2 to 10 days postoperatively. Conclusions: Among low-risk women with a postoperative complication, all cases requiring relaparotomy and medically treated uterine atony were suspected within 24 hours after surgery. Discharge 24 hours after planned cesarean section seems safe in low-risk patients.

Analysis and treatment of delayed hemorrhage after partial nephrectomy

Objective: To explore the causes of delayed hemorrhage after partial nephrectomy and its prevention and treatment methods. Methods: Clinical data for 64 cases of patients who received partial nephrectomy from August of 2010 to December of 2015 were retrospectively analyzed;whereas, 3 cases of patients (4.7%) had delayed hemorrhage, including 1 case of male patient and 2 cases of female patients. Then, compared them with patients with no hemorrhage to explore the risk factors for hemorrhage after partial nephrectomy. Results: Three cases of patients showed a large volume of gross hematuria in 7-22 days (the average was 16.3 days) after partial nephrectomy, with blood pressure and hemoglobin (HGB) decreased. 2 cases of patients with hemorrhage were given blood transfusion and conservative treatment, and patients' conditions were improved obviously. The other patient was given super-selective renal artery embolization (SRAE), with renal arteriography indicating the presence of pseudoaneurysm. Hematuria disappeared after surgery. In comparison with the non-hemorrhage group, warm ischemia time was longer in the hemorrhage group, and the difference was of statistical significance (p < .05). Conclusions: Hemorrhage occurred after partial nephrectomy is mostly delayed. Once the type of complications happens, it is required to provide a timely treatment. Super-selective renal artery embolization (SRAE) is a safe and effective treatment method for hemorrhage after partial nephrectomy.
