Group B

Twenty-six cholecystectomy patients received either an interpleural infusion of bupivacaine (Group B, n = 12) or an intravenous infusion of pethidine (Group P, n = 14) for management of postoperative pain over a three-day period. Patients in Group P experienced a significantly (P < 0.05) greater incidence of total side-effects (146) than patients in Group B (66). Pain scores (VAS) and responses to a pain questionnaire were similar for both groups; however, within Group B improvement in mean VAS scores at rest with time were more sustained. Similar reductions in FEV, and FVC from preoperative values occurred for both groups, while for Group P there were significant (P < 0.05) changes in arterial blood gases (increase in Pco2, decrease in Po2) over two days postoperatively. Patients in Group P recorded longer times to passing flatus and unaided mobilisation (P < 0.05), and required a significantly greater number of additional medications (anti-emetics and analgesics) over the postoperative period (41 vs 29, P < 0.05).

Abstract Background Tracheal intubation exposes mechanically ventilated patients to serious pulmonary complications such as ventilator-associated pneumonia (VAP). This study was conducted to compare the efficacy of manual hyperinflation in supine versus lateral decubitus position on arterial blood gases (ABG) in patients with VAP. Forty-two patients with ventilator-associated pneumonia with age range from 40 to 60 years were selected. They were randomly divided into two equal groups: group A who received manual hyperinflation from supine position and group B who received manual hyperinflation from lateral decubitus position (upper most affected). Both groups received respiratory physiotherapy. The patients received 2 sessions per day for 6 days. Outcome measures were arterial blood gases (PaO2, PaCO2, PaO2/FiO2, and SaO2). They were assessed before the 1st morning session (pre), at day 3 (post 1), and at day 6 (post 2). Results After sessions, significant changes of measured variables (PaO2, PaCO2, PaO2/FiO2, and SaO2) were obtained in both groups (P < 0.05, in all variables) and by comparison between groups post-intervention; a significant difference was observed between both groups in measures of oxygenation in favor of group B (P < 0.05), whereas there was a non-significant difference in the PaC02 between both groups (post 1 P = 0.52 and post 2 P = 0.33). Conclusion It was concluded that effect of the bag squeezing on arterial blood gases in patients with ventilator-associated pneumonia from lateral decubitus position was more effective than from supine position.

The objective of the study was to compare epidural and systemic tramadol for postoperative analgesia in bitches undergoing ovariohysterectomy. Twenty animals, randomly divided into two groups, received either epidural (EPI) or intramuscular (IM) tramadol (2 mg/kg) 30 min before anesthetic induction. Analgesia, sedation, cardiorespiratory parameters, end-tidal isoflurane, blood catecholamines and cortisol, and arterial blood gases were measured at different time points up to 24 hr after agent administration. There were no differences between the two groups regarding cardiorespiratory parameters, end-tidal isoflurane, and pain scores. Two dogs in the IM and one in the EPI group required supplemental analgesia. Cortisol was increased (P&lt;0.05) at 120 min (3.59 μg/dL and 3.27μg/dL in the IM and EPI groups, respectively) and 240 min (2.45 μg/dL and 2.54μg/dL in the IM and EPI groups, respectively) compared to baseline. Norepinephrine was also increased (P&lt;0.05) at 120 min in both groups compared to baseline values. Epinephrine values were higher (P&lt;0.05) in the IM group compared with the EPI group at 50 min, 120 min, and 1,440 min after tramadol administration. Epidural tramadol is a safe analgesic, but does not appear to have improved analgesic effects compared with IM administration.

Abstract Background: The minimal effective analgesic concentration of opioids required for satisfactory analgesia may differ significantly among the patients. Genetic factors may contribute to the variable response to opioids by affecting their pharmacokinetics or pharmacodynamics. Methods: Ninety nine patients undergoing abdominal surgery with colorectal anastomosis because of colorectal carcinoma were enrolled in the present study. C34535T was genotyped in all subjects and the patients were divided into three groups according to their genotype: CC-wild type homozygous, CT-mutant heterozygous and TT-mutant homozygous. Intravenous fentanyl, patient controlled analgesia was provided postoperatively for pain control in the first 24 hour after surgery. Opioid consumption, pain scores and the adverse side effects were evaluated. Results: Our main result is that the patients in the CC genotype group consumed significantly more fentanyl (375.0 μg ± 43.1) than the patients in the TT group (295.0 μg ± 49.1) and the CT (356.4 μg ± 41.8) group in the treatment of postoperative pain. The patients in the TT group had lower VAS scores at 6h, 12h, 18 h and 24h postoperatively. There were no significant differences in the side effects among the three groups regarding the vomiting and the sedation score. The patients in the TT group had more frequently nausea score 1, than the patients in the other two groups. Conclusion: Our study indicates that the C3435T SNPs of the ABCB1 gene is associated with differences in the opioid sensitivity. The ABCB1 polymorphism may serve as an important genetic predictor to guide the acute pain therapy in postoperative patients.

BBackground: A postoperative patient suffers from pain the best relief of which is a clinician’s duty. Till date very few studies have been conducted for comparison of paracetamol and diclofenac as analgesics. As a result a comparative study between Paracetamol and Diclofenac was carried out. The aim of the study was to compare the efficacy and side effects of intravenous Paracetamol and intravenous Diclofenac in patients undergoing major abdominal open surgeries in obstetrics and gynaecology. The study was conducted to assess the postoperative visual analogue pain scores (VAS) and total analgesic requirement in the first 24 hours and also to study the total requirement of additional analgesics despite administration of either Paracetamol or Diclofenac in postoperative period.Methods: 100 patients satisfying the inclusion/exclusion criteria were recruited for the study. They were divided into two groups of 50 each. Group A was given IV Paracetamol 6 hourly for 48 hours starting 2 hours after surgery. Group B was given IV Diclofenac 8 hourly for 48 hours starting 2 hours after surgery. Patients were assessed for pain relief by visual analogue scale (VAS) of zero to ten after 6 hours, 12 hours, 24 hours and 48 hours of surgery by asking the patient to point the position on the 100 mm scale.Results: The results revealed that when we compared the VAS scores between the 2 Groups at different time intervals, it showed that at 24 hours and 48 hours VAS score in the Diclofenac Group was significantly less than the Paracetamol Group. The main side effects were nausea and vomiting in both the groups. There was more nausea and vomiting in Diclofenac group compared to Paracetamol group.Conclusions: It was concluded that at 24 hour and 48 hour pain reduction was more in the Diclofenac group as compared to Paracetamol group, but the side effects were more in the Diclofenac group compared to Paracetamol group.

Category: Ankle, Pain medicine Introduction/Purpose: Even though bone surgery is very painful after operation, there is no established method to control postoperative pain due to efficacy and side effects. Ultrasound-guided peripheral nerve block (PNB) and nonsteroidal anti- inflammatory drugs (NSAIDs) patient controlled analgesia (PCA) can effectively control pain and reduce side effects. Methods: We conducted a prospective study of 150 patients over 18 years of age who underwent bone surgery from June 2018 to December 2018. All operations were performed under anesthetic ultrasound-guided PNB and additional PNB was performed to control postoperative pain. Among the 120 patients who participated in the final study, NSAIDs PCA was used in group A (65 patients) and NSAIDs PCA was not used in group B (55 patients) for pain control. Postoperative management except PCA was same in both groups. Pain scores are measured at 6, 12, 18, 24, 36, 48, and 72 hours after the operation and they were compared using visual analogue scale (VAS) pain scores. Survey was done on satisfaction of patients, and their willingness to reconsider same method of pain control when they undergo same surgery next time. Also, we evaluated possible side effects that might happen during process of controlling pain. Results: VAS pain score were significantly different only at 24 h postoperatively (p=0.004). In Group A, three patients were prescribed 3 amples of pethidine intramuscular injection as rescue analgesic. In group B, 35 patients were prescribed 50 amples of pethidine and 12 patients of them were received additional 18 amples of ketorolac intramuscular injection as rescue analgesic(p=0.000). In group A, all patients were satisfied with the pain control method, but 5 of the group B patients were dissatisfied (p=0.001). 3 patients responded to severe pain after operation and 2 of them due to postoperative nausea and vomiting (PONV). In group A, there were no patients complaining of PONV, but in group B, 5 patients complained of symptoms (p=0.018), and 3 of them were prescribed additional antiemetics (p=0.093). Conclusion: Combined use of ultrasound-guided PNB and NSAIDs PCA seems to be an effective postoperative pain control method in foot and ankle surgery. Because, pain can be effectively controlled and PONV can be reduced.

AbstractPost cardiac arrest syndrome is associated with high morbidity and mortality, which is related not only to a poor neurological outcome but also to respiratory and cardiovascular dysfunctions. The control of gas exchange, and in particular oxygenation and carbon dioxide levels, is fundamental in mechanically ventilated patients after resuscitation, as arterial blood gases derangement might have important effects on the cerebral blood flow and systemic physiology.In particular, the pathophysiological role of carbon dioxide (CO2) levels is strongly underestimated, as its alterations quickly affect also the changes of intracellular pH, and consequently influence metabolic energy and oxygen demand. Hypo/hypercapnia, as well as mechanical ventilation during and after resuscitation, can affect CO2 levels and trigger a dangerous pathophysiological vicious circle related to the relationship between pH, cellular demand, and catecholamine levels. The developing hypocapnia can nullify the beneficial effects of the hypothermia. The aim of this review was to describe the pathophysiology and clinical consequences of arterial blood gases and pH after cardiac arrest.According to our findings, the optimal ventilator strategies in post cardiac arrest patients are not fully understood, and oxygen and carbon dioxide targets should take in consideration a complex pattern of pathophysiological factors. Further studies are warranted to define the optimal settings of mechanical ventilation in patients after cardiac arrest.

Calming Effect

Pranayama is a Yogic breathing practice which is known experientially to produce a profound calming effect on the mind. In an experiment designed to determine whether the mental effects of this practice were accompanied by changes in the arterial blood gases, arterial blood was drawn from 10 trained individuals prior to and immediately after Pranayama practice. No significant changes in arterial blood gases were noted after Pranayama. A neural mechanism for the mental effects of this practice is proposed.
