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.

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.

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.

Comparison of bolus remifentanil-propofol versus bolus fentanyl-propofol for dilatation and sharp curettage

BACKGROUND AND OBJECTIVE

The study was conducted to determine whether bolus administrations of remifentanil-propofol could provide adequate analgesia and similar patient comfort with a faster recovery profile compared with bolus administrations of fentanyl-propofol during dilatation and sharp curettage.

METHODS

The patients were randomized to a remifentanil group (n=36) or fentanyl group (n=36). The remifentanil group received an IV bolus dose of 1 pg kg(-1) remifentanil. The fentanyl group received an IV bolus dose of fentanyl 0.5 microg kg(-1). The Verbal Pain Scale (VPS), modified Aldrete scores, blood pressure, heart rate, peripheric oxygen saturation, recovery time from anesthesia and adverse events during or after surgery were evaluated.

RESULTS

The groups were found to be similar in duration of the surgical procedure, anesthesia time and hemodynamic variables and VPS scores. Patients in the remifentanil group recovered from anesthesia earlier. Modified Aldrete scores were higher in the remifentanil group at 5 and 10 min postoperatively. The frequency of perioperative adverse events did not differ significantly between the groups.

CONCLUSIONS

Bolus injections of remifentanil appear to be a safe and effective alternative to fentanyl, producing faster recovery in providing analgesia during dilatation and sharp curettage procedures.
