Dieulafoy lesion is an abnormally large calibered submucosal artery associated with a minute mucosal defect in the gastrointestinal mucosa. It is a rare cause of profuse, but intermittent gastrointestinal bleeding. The lesion is usually located in the stomach, although it may occur anywhere in the gastrointestinal tract. Dieulafoy lesion is extremely rare in the neonates. We report two newborn infants with a gastric Dieulafoy lesion which was treated by endoscopic epinephrine injection therapy without complication and recurrence.

OBJECTIVETo investigate the effects of dopamine and norepinephrine on the renal function in the patients with septic shock.
METHODSEighty-seven patients with septic shock were divided into three groups (group A, B, C) according to the biggest infusing rate of norepinephrine, with the infusing rate of 0.5 - 0.9, 1.0 - 1.5, 1.6 - 2.0 microg x kg(-1) x min(-1), respectively. Mean arterial blood pressure (MAP), heart rate (HR), urine output, blood urea nitrogen (BUN), creatinine (CRE), urine albumin (U-ALB) and urine beta(2)-microglobulin (Ubeta(2)-MG) as well as APACHE III score in all the patients were detected.
RESULTSBefore anti-shock therapy was given, hypotension, tachycardia and oliguria occurred in all the 87 patients, and CRE, BUN, U-ALB, Ubeta(2)-MG and APACHE III score were abnormal in most cases. With the anti-shock therapy, MAP, HR, urine output and BUN, CRE in all patients returned to normal levels gradually, and U-ALB, Ubeta(2)-MG levels and APACHE III score also restored but still remained abnormal.
CONCLUSIONSThe first aim of treating septic shock should be restoring the organ blood supply, and based on volume resuscitation, dopamine, noradrenaline and other vasoactive drugs could be combined to maintain circulatory stability.

OBJECTIVETo explore the clinical effect of low dose pituitrin in children with septic shock.
METHODSA total of 48 pediatric cases with septic shock, in whom 6 hours, conventional treatment could not reverse shock from January 2008 to December 2010, were selected for this study. The patients were divided into two groups randomly (completely random design) (control group 24, remedial group 24). The conventional treatment included antibiotics/fluid resuscitation/correcting acid-base imbalance, glucocorticoid, organ (heart/lung) support, dopamine 1 - 15 µg/(kg·min) and norepinephrine 0.5 - 2 µg/(kg·min) pumped in continuously in the control group. In initial 6 hours the same treatment was given to the remedial group, while low dose pituitrin (0.01 - 0.03 U/min) was pumped additionally during the rest of time. The therapeutic effect on correcting shock was evaluated in both groups.
RESULTSThe total effective rate was 76.2% in the remedial group and 40.0% in the control group; the mortality was 33.3% and 60% respectively. The difference between both groups was significant (P = 0.025).
CONCLUSIONLow dose pituitrin could improve the clinical effect significantly in children with septic shock in whom 6 hours conventional treatment failed to correct shock, shorten the total periods of treatment, and decrease mortality.

5.Wide-Awake Primary Flexor Tendon Repair, Tenolysis, and Tendon Transfer.
Clinics in Orthopedic Surgery 2015;7(3):275-281
Tendon surgery is unique because it should ensure tendon gliding after surgery. Tendon surgery now can be performed under local anesthesia without tourniquet, by injecting epinephrine mixed with lidocaine, to achieve vasoconstriction in the area of surgery. This method allows the tendon to move actively during surgery to test tendon function intraoperatively and to ensure the tendon is properly repaired before leaving the operating table. I applied this method to primary flexor tendon repair in zone 1 or 2, tenolysis, and tendon transfer, and found this approach makes tendon surgery easier and more reliable. This article describes the method that I have used for tendon surgery.

We performed a prospective, randomized, and double-blind study comparing the top-up effects of 2% lidocaine/100 microgram fentanyl/epinephrine (n=31) and 2% lidocaine/saline/epinephrine (n=30) when extending an epidural labor analgesia using low-dose ropivacaine and fentanyl. Survival analysis for the sensory blocks to the T4 level showed no statistically significant differences in onset time to T4 between the 2 groups. Onset times (min) to T4-sensory blocks for cold and pinprick were not different between the two groups. However, median maximum sensory level in the lidocaine-fentanyl group (T1 for cold and T2 for pinprick) was significantly higher than that in the lidocaine-saline group (T3 and T4, respectively). The lidocaine-fentanyl group exhibited less visceral pain (6.5% vs. 36.7%), less supplementation of lidocaine (6.5% vs. 43.3%), and less nausea (6.5% vs. 26.7%) compared with the lidocaine-saline group during the intraoperative period. It is concluded that adding fentanyl to 2% lidocaine does not speed up the onset of the block when the onset is tested with cold or sharp pinprick but improves the quality of analgesia with fewer side effects in emergency top-up for cesarean section.

OBJECTIVETo study the effects of dopamine and phenylephrine for treatment of hypotension during cesarean section under combined spinal epidural anesthesia (CSEA) on the stereology of the placenta.
METHODSForty puerperants undergoing cesarean section under CSEA were randomly divided into dopamine group and phenylephrine group. Ropivacaine (16 mg) was administered immediately after spinal anethesia. Blood pressure was maintained near the baseline by adjusting the drug infusion rate. Fetal blood gas, Apgar score, and placental villus microvascular stereological changes were observed during the operation.
RESULTSThe microvascular density was significantly lower in dopamine group than in phenylephrine group (P<0.05). Phenylephrine group showed significantly lower umbilical artery blood pH than dopamine group (P<0.05). The Apgar score and blood pressure were comparable between the two groups (P>0.05). Compared to the baseline, both of the two groups showed significantly lowered heart rate during the operation (P<0.01).
CONCLUSIONDopamine is associated with the risk of fetal acidosis. Phenylephrine is helpful for preventing hypotension by increasing placental blood flow and improving oxygen supply to ensure maternal and fetal safety during cesarean section.

Terlipressin is a synthetic analogue of vasopressin, which has been used in the treatment of acute variceal hemorrhage. In contrast to vasopressin, terlipressin can be administered as intermittent injections instead of continuous intravenous infusion. Thus, it has a less adverse reaction than vasopressin. We report a case of ischemic skin complication in a cirrhotic patient treated with terlipressin. A 71-year-old man with liver cirrhosis was admitted because of hematemesis and melena. He was commenced on terlipressin at a dose 1 mg every 6 hours for the treatment of varicieal bleeding. After 36 hours of treatment, skin blistering and ecchymosis was noted on the skin of his upper thigh, scrotal area and trunk. We found that terlipressin was a possible cause of ischemic skin complication based on the skin biopsy finding. Terlipressin may induce a complication of the ischemic event. In spite of rarity, special attention needs to paid on the peripheral ischemic complication of terlipressin.

Nonocclusive mesenteric ischemia (NOMI) is known to occupy about 25+ACU- to 60+ACU- of intestinal infarction. NOMI has been reported to be responsible for 9+ACU- of the deaths in the dialysis population and the postulated causes of NOMI include intradialytic hypotension, atherosclerosis and medications, such as diuretics, digitalis and vasopressors. Clinical manifestations, such as fever, diarrhea and leukocytosis, are nonspecific, which makes early diagnosis of NOMI very difficult. Case: A 66-year-old woman on maintenance hemodialysis for 5 years was admitted with syncope, abdominal pain and chilly sensation. Since 7 days prior to admission, blood pressure on the supine position during hemodialysis had frequently fallen to 80/50 mmHg. Four days later, she complained of progressive abdominal pain. Rebound tenderness and leukocytosis (WBC 13900/mm3) with left shift were noted. Stool examination was positive for occult blood. Abdominal CT scan showed a distended gall bladder with sludge. Under the impression of acalculous cholecystitis, she was operated on. Surgical and pathologic findings of colon colon were compatible with NOMI. Because of recurrent intradialytic hypotension, we started midodrine 2.5 mg just before hemodialysis and increased the dose up to 7.5 mg. After midodrine therapy, blood pressure during dialysis became stable and the symptoms associated with hypotension did not recur. CONCLUSION: As NOMI may occur within several hours or days after an intradialytic hypotensive episode, abdominal pain should be carefully observed and NOMI should be considered as a differential diagnosis. In addition, we suggest that midodrine be considered to prevent intradialytic hypotensive episodes.

This is a report on a case of severe skin necrosis in a vasodilatory septic shock patient after the infusion of low-dose vasopressin through a central venous catheter. An 84-year-old male was hospitalized for edema on both legs at Asan Medical Center, Seoul, Korea. On hospital day 8, the patient began to complain of dyspnea and he subsequently developed severe septic shock caused by E. coli. After being transferred to the medical intensive care unit, his hypotension, which was refractory to norepinephrine, was controlled by an infusion of low-dose vasopressin (0.02 unit/min) through a central venous catheter into the right subclavian vein. After the infusion of low-dose vasopressin, severe skin necrosis with bullous changes developed, necessitating discontinuation of the low-dose vasopressin infusion. The patient expired from refractory septic shock. Although low-dose vasopressin can control hypotension in septic shock patients, low-dose vasopressin must be used with caution because ischemic complications such as skin necrosis can develop even with administration through a central venous catheter.
