Effect of local infiltration analgesia, peripheral nerve blocks, general and spinal anesthesia on early functional recovery and pain control in unicompartmental knee arthroplasty.

Background: The aim of the study was to analyze the effect of local infiltration analgesia (LIA), peripheral nerve blocks, general and spinal anesthesia on early functional recovery and pain control in primary unicompartmental knee arthroplasty (UKA).

Methods: Between January 2016 until August 2016, 134 patients underwent primary UKA and were subdivided into four groups according to their concomitant pain and anesthetic procedure with catheter-based techniques of femoral and sciatic nerve block (group GA&FNB, n = 38) or epidural catheter (group SP&EPI, n = 20) in combination with general anesthesia or spinal anesthesia, respectively, and LIA combined with general anesthesia (group GA&LIA, n = 46) or spinal anesthesia (group SP&LIA, n = 30). Outcome parameters focused on the evaluation of pain (NRS scores), mobilization, muscle strength and range of motion up to 7 days postoperatively.

Effect of local infiltration analgesia, peripheral nerve blocks, general and spinal anesthesia on early functional recovery and pain control in total knee arthroplasty.

Background: Postoperative pain control and enhanced mobilization, muscle strength and range of motion following total knee arthroplasty (TKA) are pivotal requisites to optimize rehabilitation and early recovery. The aim of the study was to analyze the effect of local infiltration analgesia (LIA), peripheral nerve blocks, general and spinal anesthesia on early functional recovery and pain control in primary total knee arthroplasty.

Methods: Between January 2016 until August 2016, 280 patients underwent primary TKA and were subdivided into four groups according to their concomitant pain and anesthetic procedure with catheter-based techniques of femoral and sciatic nerve block (group GA&FNB, n = 81) or epidural catheter (group SP&EPI, n = 51) in combination with general anesthesia or spinal anesthesia, respectively, and LIA combined with general anesthesia (group GA&LIA, n = 86) or spinal anesthesia (group SP&LIA, n = 61).

Leukodepletion of autologous whole blood has no impact on perioperative infection rate and length of hospital stay.

Background: Several mechanisms have been proposed as possible causes of transfusion-related immunomodulation (TRIM) after allogeneic transfusion. If one of these mechanisms, the release of mediators of immunity and inflammation ("biologic response modifiers"[BRMs]) from disintegrating blood cells during storage of blood products, really causes TRIM, it should in principle also occur after autologous transfusion. As a consequence, prestorage leukoreduction of autologous blood should be able to prevent the clinical consequences of TRIM after autologous transfusion.

[Operation room management in quality control certification of a mainstream hospital].

We report the results of our study concerning the organisation of operating room (OR) capacity planned 1 year in advance. The use of OR is controlled using 2 global controlling numbers: a) the actual time difference between the expected optimal and previously calculated OR running time and b) the punctuality of starting the first operation in each OR. The focal point of the presented OR management concept is a consensus-oriented decision-making and steering process led by a coordinator who achieves a high degree of acceptance by means of comprehensive transparency.

[Recombinant activated factor VIIa for treatment of traumatic liver rupture].

Hepatic rupture after blunt abdominal trauma may lead to severe bleeding, depletion and consumption of clotting factors, with the risk of packing to defer the definitive operation. We report two cases of hepatic rupture after blunt trauma with intrahepatic hematoma and severe intraabdominal bleeding. In both cases the bleeding could be stopped by early intervention with recombinant activated factor VIIa (rFVIIa).

Remifentanil for analgesia during retrobulbar nerve block placement.

Background And Objectives: Patients undergoing eye surgery under regional anaesthesia often require concomitant medication for analgesia and comfort. Remifentanil, with its ultra-short acting-profile, may be useful to reduce pain during retrobulbar nerve block for cataract surgery.

Methods: We performed a prospective, randomized, double-blind study to compare the efficacy of remifentanil for analgesia during retrobulbar nerve block placement.

[Unusual complication after combined spinal/epidural anaesthesia].

An 31-year-old women with a long history of back pain without neurological symptoms underwent a caesarean section during the 36th week of pregnancy with combined spinal-epidural anaesthesia. Indication was the increasingly severe back pain. She delivered a normal healthy boy.

[Reduction of severe cardiac complications during implantation of cemented total hip endoprostheses in femoral neck fractures].

Intraoperative circulatory and pulmonary problems occuring during the repair of femoral neck fractures with cemented hip arthroplasty are a common problem, that cannot be ultimately explained. As a possible reason for this problem is air embolism during the polymerisation of the methylmethacrylat discussed. We started a prospective randomised clinical examination with 72 patients to prove the efficiency of palacos mixed in vacuum, with respect to the reduction of severe cardiovascular complication during endoprosthetic repair of femoral neck fractures.
