Shoulder tip pain after cesarean section: General versus spinal anesthesia.

Background and Aim: Shoulder tip pain is a common but overlooked complication during the postoperative cesarean section. In this study, we aimed to investigate the relationship between the anesthesia method and the incidence of shoulder tip pain. Patients and Methods: In this randomized clinical study, 117 patients who underwent cesarean section were divided into two groups as spinal anesthesia and general anesthesia. The demographic characteristics, the presence, the severity of shoulder tip pain, and also analgesic consumption in the first 24 hours were compared. Results: The incidence of shoulder tip pain was significantly higher in the spinal anesthesia group than in the general anesthesia group (p = 0.032). While there was no statistically significant difference in terms of the number of patients who needed opioid treatment within the first 24 hours between patients with and without STP, a statistically significant difference was observed in terms of the use of nonsteroidal anti-inflammatory drugs (P < 0.001). Conclusions: This study shows that the frequency and severity of shoulder pain are higher in women who have had cesarean section under spinal anesthesia, compared to those who had received general anesthesia.

First direct human-to-cat transmission of the SARS-CoV-2 B.1.1.7 variant.

A highly transmissible severe acute respiratory coronavirus 2 (SARS-CoV-2) caused the coronavirus diseases 2019 (COVID-19) pandemic, which resulted the highest morbidity and mortality rates among SARS-CoV and MERS-CoV. SARS-CoV-2 B.1.1.7 variant indicated the higher transmission among human-to-human and increasing hospitalisation. SARS-CoV-2 infection was observed in domestic animals showing human-to-pet transmission. In the current study, we report the first direct known human-to-cat transmission of the SARS-CoV-2 B.1.1.7 variant within the same family. Previous findings showed that companion animals can get infected by COVID-19 patients after 3-6 weeks; however, according to our molecular findings, the cat was infected by the viral variant at the same period. Moreover, B.1.1.7 infection caused and developed several clinical symptoms including cardiac and ocular abnormalities. Overall, our findings determined the first direct and high transmission ability of the B.1.1.7 variant from COVID-19 affected family members to cat. This result showed that the SARS-CoV-2 B.1.1.7 variant could have the highest transition capacity from human to domestic cat as shown for human-to-human. The governmental or worldwide policies should consider more detailed against the war with COVID-19 pandemic.

A new COVID-19 prediction scoring model for in-hospital mortality: experiences from Turkey, single center retrospective cohort analysis.

OBJECTIVE: Although many studies reported prognostic factors proceeding to severity of COVID-19 patients, in none of the article a prediction scoring model has been proposed. In this article a new prediction tool is presented in combination of Turkish experience during pandemic. MATERIALS AND METHODS: Laboratory and clinical data of 397 over 798 confirmed COVID-19 patients from Gülhane Training and Research Hospital electronic medical record system were included into this retrospective cohort study between the dates of 23 March to 18 May 2020. Patient demographics, peripheral venous blood parameters, symptoms at admission, in hospital mortality data were collected. Non-survivor and survivor patients were compared to find out a prediction scoring model for mortality. RESULTS: There was 34 [8.56% (95% CI:0.06-0.11)] mortality during study period. Mean age of patients was 57.1±16.7 years. Older age, comorbid diseases, symptoms, such as fever, dyspnea, fatigue and gastrointestinal and WBC, neutrophil, lymphocyte count, C-reactive protein, neutrophil-to-lymphocyte ratio of patients in non-survivors were significantly higher. Univariate analysis demonstrated that OR for prognostic nutritional index (PNI) tertile 1 was 18.57 (95% CI: 4.39-78.65, p<0.05) compared to tertile 2. Performance statistics of prediction scoring method showed 98% positive predictive value for criteria 1. CONCLUSIONS: It is crucial to constitute prognostic clinical and laboratory parameters for faster delineation of patients who are prone to worse prognosis. Suggested prediction scoring method may guide healthcare professional to discriminate severe COVID-19 patients and provide prompt intensive therapies which is highly important due to rapid progression leading to mortality.

Sedoanalgesia for cardioversion: comparison of alfentanil, remifentanil and fentanyl combined with propofol and midazolam: a prospective, randomized, double-blind study.

OBJECTIVE: Electrical cardioversion (EC) is a short but painful procedure to restore sinus rhythm. The aim of this study is to compare the effect of fentanyl, remifentanil and alfentanil in association with propofol and midazolam for elective EC. PATIENTS AND METHODS: Ninety-nine patients older than 18-years, American Society of Anesthesiologists I/II/III grades undergoing elective EC were randomized into 3 groups. All patients received 2 mg midazolam and propofol (0.5 mg/kg). Group A received alfentanil (5 µg/kg i.v. bolus), Group F received fentanyl (0.5 µg/kg i.v. bolus) and Group R received remifentanil (0.25 µg/kg i.v. bolus). Hemodynamics and respiratory variables [Heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), SpO2, respiratory rate (RR)], and Modified Aldrete recovery score (MARS) were assessed at six different time points (baseline, right after EC, and 3rd min, 5th min, 10th min, 30th min following EC). Also, induction times (time to reach RSS to 5) and recovery times (time to reach MARS to 8) were recorded. The incidence of respiratory depression, bradycardia, hypotension and adverse effects were also recorded. RESULTS: Hemodynamic variables were similar in all groups. SpO2 values in Group R were significantly lower at 3rd min (p = 0.005). Induction and recovery times were longest in Group F. There were significant differences at 3rd, 5th and 10th minute MARS values between groups. The incidence of hypotension and bradycardia were similar in all groups (p > 0.05) but respiratory depression was higher in Group R (p = 0.047). CONCLUSIONS: Propofol alfentanil combination has more beneficial advantages in their rapid onset, early recovery time and less respiratory depression than remifentanil and fentanyl.

Polidocanol (Lauromacrogol 400) has anti-angiogenic effects in vitro and in vivo.

OBJECTIVE: Polidocanol is the most frequently used sclerosant for sclerotherapy all around the world. Our experimental research aims to find out the angiogenic effects of Polidocanol. MATERIALS AND METHODS: Angiogenic activity of polidocanol was examined in vivo in the chick chorioallantoic membrane (CAM) model, cell viability assay (human umbilical vein endothelial cells - HUVECs) and in vitro tube formation assay of HUVECs. RESULTS: In CAM assay, a significant decrease on CAM vessel growth was observed after the application of polidocanol solutions. Vessel growth inhibition was strongly dose-dependent. There was a cytotoxic effect on HUVECs in the presence of polidocanol observed with MTT assay (p < 0.05). In the tube formation assay, statistically significant decrease in tube formation was observed in polidocanol group. It was found that polidocanol had an anti-angiogenic effect (p < 0.05). The results provide evidence that polidocanol decreases angiogenesis and has a cytotoxic effect on ECs. CONCLUSIONS: These results provide evidence that Polidocanol (lauromacrogol 400) have strong anti-angiogenic effects in vitro and in vivo. Further researches needed to reveal early and long-term effects of polidocanol in the human vascular system and new treatment approach as an anti-angiogenic therapy.

Acute high dose-fentanyl exposure produces hyperalgesia and tactile allodynia after coronary artery bypass surgery.

OBJECTIVE: Opioid-induced hyperalgesia is well known complication of acute high dose and chronic opioid therapy. In this study, we evaluated development of opioid-induced hyperalgesia following intraoperative short-term use of µ-opioid agonist fentanyl after coronary artery bypass surgery. PATIENTS AND METHODS: 100 patients undergoing elective coronary artery bypass graft surgery is divided into two groups. In group I (low dose), anesthesia was induced with propofol 1-2.5 mg/kg and fentanyl 2 mcg/kg, in group II (high dose) fentanyl 40-70 mcg/kg was used. In group I, propofol 5-10 mg/kg/h, fentanyl 1-3 mcg/kg/h, in group II fentanyl 5-10 mcg/kg/h was used for maintenance of anesthesia. The tactile and thermal thresholds were measured before surgery and in 1st, 3rd and 7th postoperative days by using Von Frey filaments and a thermal source, respectively. RESULTS: Tactile thresholds were significantly decreased at the first (6,08±0.21 and 3.76±0.13 g; p<0.001) and third (6.76±0.24 and 4.96±0.16 g; p<0.001) postoperative days compared to baseline preoperative values (7.72±0.26, and 7.60±0.21 g; p=816) in two groups. Postoperative 1st (13.45±0.33 and 10.05±0.24 sec; p<0.001) and 3rd day (14.77±0.28 and 13.17±0.26 sec; p<0.001) assessments showed a statistically significant thermal hyperalgesia compared to the preoperative baseline values (16.67±0.51 and 16.45±0.42 sec; p=0.997) in two groups. This decrease in both tactile and thermal thresholds returned to baseline control values at the 7th day of measurement. CONCLUSIONS: Our results showed that patients undergoing coronary artery bypass surgery receiving fentanyl anesthesia developed postoperative tactile allodynia and thermal hyperalgesia and this was more prominent in high dose group.
