Administration of intravenous butorphanol after delivery of the baby can reduce pruritus that has been induced by intrathecal morphine administration in cesarean delivery with combined spinal-epidural anesthesia.
Background: Septic acute kidney injury is considered as a severe and frequent complication that occurs during sepsis. The present study was performed to understand the role of miR-22-3p and its underlying mechanism in sepsis-induced acute kidney injury.
Methods: Rats were injected with adenovirus carrying miR-22-3p or miR-NC in the caudal vein before cecal ligation. Meanwhile, HK-2 cells were transfected with the above adenovirus following LPS stimulation. We measured the markers of renal injury (blood urea nitrogen (BUN), serum creatinine (SCR)). Histological changes in kidney tissues were examined by hematoxylin and eosin (H&E), Masson staining, periodic acid Schiff staining and TUNEL staining. The levels of IL-1β, IL-6, TNF-α and NO were determined by ELISA assay. Using TargetScan prediction and luciferase reporter assay, we predicted and validated the association between PTEN and miR-22-3p.
Results: Our data showed that miR-22-3p was significantly down-regulated in a rat model of sepsis-induced acute kidney injury, in vivo and LPS-induced sepsis model in HK-2 cells, in vitro. Overexpression of miR-22-3p remarkably suppressed the inflammatory response and apoptosis via down-regulating HMGB1, p-p65, TLR4 and pro-inflammatory factors (IL-1β, IL-6, TNF-α and NO), both in vivo and in vitro. Moreover, PTEN was identified as a target of miR-22-3p. Furthermore, PTEN knockdown augmented, while overexpression reversed the suppressive role of miR-22-3p in LPS-induced inflammatory response.
Conclusions: Our results showed that miR-22-3p induced protective role in sepsis-induced acute kidney injury may rely on the repression of PTEN.
This randomized, double-blinded, placebo-controlled trial investigated the effect of continuous epidural butorphanol on intrathecal morphine-related pruritus in patients undergoing cesarean section. Eighty-three patients undergoing elective cesarean section under spinal anesthesia (1.5 mL of isobaric bupivacaine 0.5 % and 0.1 mg of preservative-free morphine) were enrolled in this study. Subjects were randomized to receive epidural butorphanol (n = 43) or normal saline combined bupivacaine (n = 40). In the study group, after the umbilical cord was clamped, patients were administered an epidural loading dose of 1 mg followed by a 48-h infusion of 0.004 % butorphanol with 0.1 % bupivacaine at a rate of 2 mL/h. In the normal saline group, saline was used for the loading dose and the infusion 0.1 % bupivacaine at a same rate. Postoperatively, a blinded observer recorded the incidence/severity of pruritus, visual analog pain scores and sedation level at 1, 3, 6, 9, 12, 24 and 48 h. The 48-h consumption of breakthrough analgesic (tramadol) was also noted. The primary outcome was the incidence of pruritus at 48 h. At 48 h, the incidence of pruritus was significantly lower in the butorphanol group (16.3 vs. 52.5 %; P < 0.001). Furthermore, compared with the normal saline group, the intensity of pruritus was also decreased with epidural butorphanol at 3, 6 and 9 h (all P ≤ 0.008). The pain scores were significantly lower at 12, 24 and 48 h (all P < 0.05) in the butorphanol groups. Patients only receiving bupivacaine required a higher cumulative dose of tramadol (37.5 ± 62.8 vs. 9.3 ± 36.6; P = 0.014). In patients undergoing elective cesarean section, continuous epidural butorphanol with bupivacaine decreases the incidence and severity of intrathecal morphine-related pruritus without adversely affecting the quality of postoperative analgesia.
Oesophageal foreign body is an emergency situation. Once oesophageal perforation occurs, damage and subsequent infection involving surrounding tissue or organs may ensue. We present here a rare case of aorto-oesophageal fistula which was treated with challenges. An old lady with fishbone induced oesophageal perforation, aortic pseudoaneurysm and mediastinal haematoma was treated with great vessel stent-graft placed in aortic arch, and the fish bone was removed under endoscopy thereafter. During the early follow-up period, part of the graft stent was discovered in the oesophageal perforation with no haemorrhage. The patient is still in good condition during follow-up.
Background
The aim of this study is to evaluate analgesic efficacy of pericapsular nerve group (PENG) block in patients with intertrochanteric femur fracture (IFF).
Methods
This double-blinded randomized controlled trial in patients with IFF scheduled for proximal femoral nail antirotation (PFNA) between December 2020 and November 2021. The primary outcome was VAS scores during exercising at 6 h after surgery; secondary outcomes were pain during exercising and rest, intraoperative dose of remifentanil, cumulative dose of postoperative fentanyl, postoperative analgesia satisfaction scores, and ratio of quadriceps weakness.
Results
A total of 50 patients were randomly divided into PENG block group (n = 25) or fascia iliaca compartment block (FICB) group (n = 25). Exercising VAS scores at 6 h after surgery were significantly lower in PENG block group than that in FICB group (2 (2, 4) vs. 6 (4, 7), P < 0.001). The intraoperative dose of remifentanil and cumulative dose of postoperative fentanyl by patient-controlled intravenous analgesia within 24 h after surgery in PENG block group were significantly lower than in FICB group (both P < 0.001). Postoperative analgesia satisfaction scores in PENG block group were significantly higher than those in FICB group (P = 0.016). The ratio of quadriceps weakness at 6 h after surgery was significantly higher in FICB group than PENG block group (48% vs. 0%, P < 0.001).
Conclusions
Compared to FICB, ultrasound-guided PENG block may provide better postoperative pain relief in patients with IFF, with less pronounced quadriceps weakness.
BACKGROUND
Peripheral regional block combined with general anesthesia might be a preferable anesthetic regimen for elderly patients undergoing total hip arthroplasty.
AIM
To investigate whether ultrasound-guided, direct suprainguinal injection for fascia iliaca block accelerated recovery after general anesthesia and relieved postoperative pain after total hip arthroplasty.
METHODS
Patients who underwent total hip arthroplasty under general anesthesia in 2015 or 2019 at The Second Affiliated Hospital of Xuzhou Medical University were retrospectively analyzed. The patients were grouped based on whether preoperative suprainguinal fascia iliaca block was performed or not. The time to tracheal extubation and time spent in the post-anesthesia care unit (PACU), intraoperative remifentanil dosage, fentanyl consumption in the PACU, postoperative cumulative fentanyl consumption within 48 h after operation, visual analogue scale at rest and during movement on the first and second days after surgery, and adverse reactions were compared.
RESULTS
Thirty-one elderly patients who underwent total hip arthroplasty were included in the study (block group,
n
= 16; no-block group,
n
= 15). The visual analog scale scores at rest and during movement on the first and second days were significantly lower in the block group than in the no-block group (all
P
< 0.05). Compared with the no-block group, the intraoperative remifentanil dosage was lower, the time to tracheal extubation and the time spent in the PACU were shorter in the block group (all
P
< 0.01). Fentanyl consumption in the PACU and postoperative cumulative fentanyl consumption in 48 h after operation were lower in the block group (all
P
< 0.01). The incidence of dizziness was higher in the no-block group than in the block group (
P
= 0.037).
CONCLUSION
Ultrasound-guided, direct suprainguinal injection for fascia iliaca block led to faster recovery after general anesthesia and early postoperative pain relief in elderly patients undergoing total hip arthroplasty.
